Just found this, which may be of interest - the Sunbeam was at Loughborough Engineering College (now Loughborough University) in 1940!

 

 

According to JISC their archive is still on site so there might be something more to find about it: https://archiveshub....16-fbec1c23959f

Good find Vitesse2 !

[Pullman99]

Thanks Vitesse2 from me too!     Fascinating to know that there was a connection to Loughborough in wartime and this all adds to the story and timeline for the Sunbeam  

[Vitesse2]

I wonder if part of the reason was to get it to a safer location in case of air raids? Although it's before the Battle of Britain and the more general autumn/winter Blitz which initially targeted known aircraft factories like Supermarine in Southampton and Vickers at Brooklands, the old Sunbeam factory in Wolverhampton - which is presumably where the car still lived - would likely have been a target as well, given that in 1936 it had been taken over by Fischer Bearings Ltd.

There certainly was an expectation that Wolverhampton would be bombed. My father worked at the garage of Cyril Williams, Junior TT winner, and was on firewatch some nights. He reckoned there was only ever one bomb dropped on the town. It was on a playing field - so a lost or damaged aircraft trying to head home, offloading its dangerous cargo while avoiding housing. (But there was certainly more than one bombing raid in the six years!).

 

The location of Wolverhampton meant the Luftwaffe had to cross Birmingham or Coventry to reach it, so perhaps it would be the first target to abandon if plans changed.

 

Fascinated by the Express and Star article, Vitesse2. If I may indulge more family connections, in the fifties my uncle was advertising space salesman for the newspaper. Therefore he knew the owning Graham family, including their son Doug Graham, who raced a Lotus XI. Meanwhile my father went on to repair rented radios, including that of the Stevens brothers, proprietors of AJS. They said they'd closed the business without leaving any creditors unpaid.

The National Motor Museum has compiled, courtesy of their Director of Collections Andrea Bishop, a (hopefully) definitive timeline for the movements of the Sunbeam 1000HP from 1927 and I have incorporated this below.   The car came to the then Montagu Motor Museum in 1958 and the restoration to running order continues apace at this time with the aim of returning the car to Daytona Beach in March 2027.   All being well, the first (rear) engine could be running later this year.

 

The listing for Loughborough would suggest that the Sunbeam may have stayed there until after WW2 and then, presumably, returned to the care of the Rootes Group.    The note about the Oulton Park meeting is interesting as it was after the Sunbeam had been exhibited at Goodwood as part of the launch / test of Donald Campbell's Bluebird CN7.

 

Also interesting is the note about the Melbourne International Trade Fair in early 1928.  I found an online reference to The British Trade Exhibition that was held in Melbourne from February to April in 1928. This was the first exhibition of British goods since the Melbourne International Centennial Exhibition of 1888 and the first devoted solely to British goods.   Organised by the Australian Association of British Manufactures, 175 exhibitors displayed almost one million articles from heavy industries to textiles and china (and including, presumably, the Sunbeam).   I have not yet discovered pics of this event but if any of our Australian correspondents can assist please post here!

 

Missing from the list below is mention of the Edinburgh Golden Jubilee event held on Saturday 5th October 1946

 

1927 1000hp Sunbeam appearances

 

  *EVENT test run

  *PLACE Wolverhampton, Sunbeam Moorfield Works & Staffordshire & England

  *DATE 21.2.1927

  *PERSON driver : Segrave, Henry O'Neal de Hane, Major

  *NOTE The 1000hp Sunbeam was shown to the press and employees of the company.    Segrave drove the car around the works site, where it was photographed outside the canteen. He found the engines to be remarkably flexible and the car to have satisfactory manoeuvrability.

 

  *EVENT World Land Speed Record attempt test run

  *PLACE Daytona Beach & Florida USA

  *DATE 21.3.1927

  *PERSON driver : Segrave, Henry O'Neal de Hane, Major

  *NOTE The 1000hp Sunbeam reached speeds of 100mph to 110mph on this test run, during which it proved difficult to steer. The rear brakes were inefficient and ventilation for the rear radiators was inadequate. 

      Consequently, the steering box was changed in favour of a higher geared unit, new brake shoes were fitted and larger air scoops were attached to the sides of the body. An estimated crowd of 10,000 watched this test run.

 

  *EVENT World Land Speed Record attempt test run

  *PLACE Daytona Beach & Florida USA

  *DATE 24.3.1927

  *PERSON driver : Segrave, Henry O'Neal de Hane, Major

  *NOTE The car reached a speed of 166mph (or probably higher - spectators walked on the timing strips, thus interfering with readings) and several problems became apparent. Air coming into the cockpit through the front of the car, nearly blew Segrave out of his seat and the gear change from 2nd to top was difficult. The unlined aluminium shoes of the rear brakes had melted when applied at high speed. In the week following, an aluminium bulkhead was fitted between the cockpit and front engine and the height of the wind deflecting cowl in front of the driver was increased. The gearbox selector, which had seized slightly, was freed and new brake shoes were fitted. The gear ratio of the final drive was decreased, to improve acceleration. This lowered the top speed, and would not have been done if Segrave had been aware of the timing strip problems.

 

  *EVENT World Land Speed Record attempt.

  *PLACE Daytona Beach & Florida & USA

  *DATE 29.3.1927

  *PERSON driver : Segrave, Henry O'Neal de Hane, Major

  *NOTE Segrave broke three World Land Speed Records. The flying mile was covered in 17.67 seconds at an average speed of 203.79mph, the flying kilometre in 11.02 seconds at 202.99mph or 326.68kph and the flying 5 kilometres in 55.19 seconds at 202.68mph or 326.18kph. The car reached a top speed of 207.51mph. After the 1st, northward run, all 4 wheels were changed, though the tyres were hardly worn. The return, southward run, was aided by an 18mph north-easterly wind, but a gust caused the car to swerve into the line of flag posts marking the course.   After crossing the line, Segrave closed the throttles but the car failed to slow. Running out of course, he applied the brakes, but they proved ineffective - the shoes had melted. To slow the car, Segrave drove into the water's edge. The engines kept running and he was able to drive out.

 

   *EVENT exhibition

  *PLACE Selfridge's, Oxford Street & London & England

  *PLACE Brooklands, Weybridge & Surrey & England

  *DATE 6.6.1927

  *PERSON driver : Segrave, Henry O'Neal de Hane, Major

  *NOTE Despite heavy rain, Segrave drove the 1000hp Sunbeam on demonstration runs around the Members' Hill and public enclosure. On the 2nd circuit of the enclosure, Segrave accelerated violently over the finishing straight, causing the car to skid and swerve through pooled water. He managed to get the car back under control and continued to do a clockwise lap at slow speed. This was the 1st time that the public had been able to see the car perform in Britain.    Because of the constraints imposed by the track, it ran on its rear engine only. Both before and after the display, the car was on show in the paddock.

Thank you Vitesse2.    This all adds to the story. 

 

Just been in the NMM's workshop.   This is the transfer gearbox casing in the process of being rebuilt.    The two large apertures are for the input shafts from the two Matabele engines.   New bearings have been sourced from R&M Bearings that supplied the originals!

 

 

PS:   Vitesse2 I am sending you a PM separately

Thanks Michael,

 

Greatly appreciated and, clearly, Sunbeam and its associated suppliers were making the most of exhibiting the car in Melbourne (and later Sydney).    Maybe it should make a return trip in 2028!

Latest news from Beaulieu - the project now has a dedicated Facebook page BTW - The National Motor Museum engineers have ‘unglued’ the gearbox of Land Speed Record breaker Sunbeam 1000hp and created new parts to make it run again for its 100th anniversary.

 

You can see the reassembly of the gearbox, and much else besides, in the NMM workshop here on You Tube:

 

https://www.youtube....h?v=01gt4S6sZys

 

Work revealed chipping on the gears, where the original record-breaking team struggled to get it into second gear for its landmark run at Daytona Beach.   It is the latest stage of the campaign that aims to raise £300k to complete the restoration of the car with the ambition of taking it back to Florida for the centenary of its 203 mph record in March 2027.

Latest update on the Sunbeam 1000HP restoration kindly filmed by Scarf and Goggles and on You Tube.   Link below:

 

https://www.youtube....4optrjmU&t=774s

 

At the Goodwood Festival of Speed, the National Motor Museum is running one they made earlier; the Sunbeam 350hp with which Malcolm Campbell set his first World Land Speed Record of 146.16 mph at Pendine on the 24th September 1924 (he became the first to take the record over 150mp the following year).   The museum is also running the 1967 Lotus 49 (chassis R3).    Over on the Cartier Style et Luxe concours event, the museum is displaying its 1909 Rolls-Royce 40/50 Silver Ghost.

Thank you for that. Lovely stuff !

Quick update!

 

The Transport Torque on the 27th January was extremely well attended and the short talk given by Richard Noble was most welcome as it linked the approach to record breaking technology from 100 years ago with the Sunbeam to the continuing saga of the LSR (and WSR) today.   The NMMT's Doug Hill and Ian Stanfield gave a "state of the union" address on progress on the rebuild and the good news - that was witnessed first hand during the museum tour that followed - is that the work is continuing apace with the initial stages of the reassembly of the first of the two Matabele engines.   The rear one in this case.  I will try and update this thread over the coming months.

 

 

Is there a report or copy of Richard Nobles's talk anywhere?

 

Thanks for a great thread.

The excellent Scarf and Goggles You Tube channel visited the National Motor Museum earlier this year to record a series of programmes following progress on the restoration of the Sunbeam 1000HP.

 

In this third episode - and with coverage intended to continue as we approach the centenary in 2027 of Henry Segrave's 203mph world land speed record - the NMM's Senior Engineer Ian "Stan" Stanfield discusses the history of the car's two Sunbeam Matabele V12 engines and the challenges in restoring them to running condition.   There is also a close look at the car's bodywork where more "time-capsule" discoveries are revealed.

The National Motor Museum has a Sunbeam 1000HP themed stand at this year's Goodwood Revival that starts on Friday 6th September and members of the Beaulieu team will be on hand to answer questions and provide information on the restoration.   There is a range of merchandise, including exclusive T shirts and poster, that will be on sale in support of the restoration project.  The NMM's stand is number 244 in the "Over the Road" section.

 

Meanwhile, work on the Sunbeam's chassis and the rear mounted engine continues as highlighted in  the recent series from Scarf and Goggles on You Tube (see link above)

Work on the first of the two Sunbeam Matebele engines - this is the rear mounted on - continues to make progress.    The crankshaft should be installed in the crankcase today - coincidentally the 41st anniversary of Thrust 2's land speed record in 1983 - and the Scarf and Goggles You Tube channel has also been filming the latest (Episode 4) instalment this week.

 

 

[Sterzo]

It seems almost a shame to take the beautiful crankshaft and connecting rods and hide them away inside an engine.

[Steve L]

Considering the state this engine was found to be in, have they taken steps to arrest the likely further deterioration of the second while they work on the first (if you see what I mean!)?

Some very s/h gears in that box. 2nd in particular. Case casting is far from ideal too. Though since it is all near 100 years old I guess that was ok then.

Oils arent oils Sol,, 100 y/o oil was no where near the quality of modern. I suspect use some modern synthetic in that and will change far nicer.

Recently watching the Australian Artillary museum stripping a 44 Stug F tank gearbox. The oil had totally congealed and was horrible but surprisingly the gears and bearings looked brand new. German wartime oils were generally quite poor. I suspect the tank it came from was put out of service very soon after going into service. German tanks supposedly had weak gearboxes,, that one eas big in every respect. Same place has stripped Grant tanks and the oil has came out very well after sitting for 80 years. Better oils.

The original Stug box was a corroded disaster. Probably lived in the weather on the Eastern front. New parts though come from Poland.

[Pullman99]

Considering the state this engine was found to be in, have they taken steps to arrest the likely further deterioration of the second while they work on the first (if you see what I mean!)?

The second (front) engine has had some work done including dissolving remaining deposits of congealed Castrol R.   The good news, from today the 9th January, is that reassembly work on the rear engine has progressed to the stage where the first of the four cylinder blocks has been refitted.   Quite a tricky operation given that the engine uses "master and slave" (is there a better name for these nowadays) conrods.  All working well so far but the task of retiming lies ahead.    All being well, the aim is to bench test this engine in the next few weeks and that will be the first time that a Sunbeam Matabele has been heard in action since 1927.

 

Time honoured method of gasket production when you find Halfords has closed for the day...

 

The rear engine on its workshop cradle with the first of the four three-cylinder blocks being gently installed.  The car in the background, in case anyone was wondering, is the museum's 1903 Daimler 22hp.

 

Meanwhile, components are gradually being refitted to the Sunbeam's chassis.   Current work includes the refitting of the front axle and brakes with new )non-asbestos) linings on the original bronze shoes that were fitted in the USA in March 1927 following failure of the aluminium alloy versions installed initially at Wolverhampton..   Due to cracking, newly cast brake drums are being cast for the rear assembly and will be fitted as soon as they arrive back from Bridport Foundry.   

 

[Pullman99]

Research continues on the background to the Sunbeam Matabele engines in the Sunbeam 1000HP car.   The museum is continuing to make progress with the restoration to running order and work on the first of the two engines continues apace.  As of yesterday, the blocks and crankcase have now been reassembled so it is hoped to be able to run this engine in the next couple of months. of months. This will, unless anyone knows otherwise, be the first time that anyone will have heard a Sunbeam Matabele run since 1927!

 

Four of these engines were used in two powerboats, Maple Leaf V and Maple Leaf VII built by Saunders Roe at Cowes. Of the four fitted to these racing boats, two were subsequently used in the Sunbeam 1000HP and today remain the sole surviving units of this type.

 

As mentioned, all being well, there is an intention to allow the first - the rear engine in the car - unit to be run in the coming weeks and, if the programme allows, to be able to promote this milestone to as wide an audience as possible; including those who follow historic aviation as well as motorsport.  There is a documented test flight in an Airco DH.4 during May 1918 (in place of the regular Rolls-Royce Eagle) and apparently the results were encouraging but came too late in WW1 to allow volume manufacturing to commence. It is generally believed that Sunbeam produced just 19 Matabele engines by the war's end. The last documented running of the car was as a demonstration by Sunbeam team driver Albert Divo at the French Grand Prix at Montlhèry on the 3rd July 1927

 

Following WW1, there was limited use for the Matabele although one brief exception appears to be the short-lived service starting in September 1919 from Paris to Croydon (although they may have operated to Hounslow Heath as well) run by Compagnie générale transaérienne. This small airline had a fleet of seven Nieuport-Delage NiD 30 single Matabele-engined biplanes with a passenger capacity of just four. After the loss of one aircraft over the Channel in April 1920, and further accidents as well, the type was withdrawn from service in February 1921. The airline was eventually absorbed, in 1923, into Air Union which was itself merged into Air France in 1933. It would be interesting to know if any of the company's records (or Air France archives) survive relating to this brief episode in the career of the Sunbeam Matabele.

 

And, in case anyone was wondering, this is an upturned view of the Matabele engine on its build stand and not a Daimler-Benz DB605...

 

If any Forum members can throw any light on the aviation career of the Matabele, I would love to hear more.

 

Ian

[Vitesse2]

According to WF Bradley in The Autocar, January 3rd 1920, a Matabele was one of several Sunbeam aero engines displayed at the Paris Aero Show in December 1919.

 

You're presumably aware of another article in the same magazine, June 4th 1926?

Those rods scare me with all those holes in the small end. 

Brake material,, use the best material used in historic racing. I have had rear brakes relined in whatever the best was from my local specialist. Does not bite very hard but will stand the heat without wearing out. Possibly better now as I have not had any done in 20 years. I used velvetouch 'buttons' before that and it was better than rear discs. Bit hard and never faded. BUT was expensive and wore out in 2 meetings and ofcourse fried wheelcylinders and return springs as well. Not too bad on drums. 

I feel you can still buy it ex USA, maybe. Same material in different size / shape pucks was used on clutch plates for racing. Pretty tough and did not wear out very quickly but a bit hard on flywheels and pressure plates. Again I have not had any done for 20 years. Still got one in use that was given to me!! Using a standard pressure plate.

[Pullman99]

Just been in the NMM workshop this afternoon.   Cylinder blocks now in place and the camshafts are now being refitted.  Not long, hopefully, until the sound of a Sunbeam Matabele wakes everyone up...

 

 

[Pullman99]

In the NMM workshop yesterday (Tuesday 11th February), progress on the rear Matabele continues apace with the plumbing for the air start mechanism having now been fitted.   The air pressure originally used is not recorded but tests indicate that it was not an extreme number, merely enough to get the engine to turn.    

 

The pic below shows the NMM;s Chief Engineer, Ian Stanfield, with part of the air distributor from a Sunbeam Maori, kindly loaned by Derby Museums and then Rolls-Royce Heritage Trust engine collection (they have some non-RR engines too( and from which new components have been made using the original as a pattern.   Sunbeam, almost certainly at the request of Henry Segrave and Louis Coatalen, removed the original air start components at some point after the 1927 record.

 

 

And this is where it goes...  There are separate air start valves for each bank with both being fed by a common inlet pipe from the air source.

 

 

 

 

The National Motor Museum is currently in discussion with the City of Daytona Beach and other organisations in the USA in connection with running the Sunbeam 1000HP in 2027 on the centenary of its land speed record.

[Pullman99]

Recent progress on the National Motor Museum's restoration of the Sunbeam 1000HP land speed record car shows the first (rear) of the two engines getting close to completion.    The sound of a V-12 Matabele may be heard again in the land - after probably close to a hundred years - quite soon.

 

The air start system is now plumbed in and has been tested but there remain a few issues to resolve to ensure reliability.

 

 

In the meantime, a flywheel from a well-known fleet favourite of the 1990s and a high performance starter motor have been fitted temporarily to the test rig to avoid relying solely on the air system during the initial engine running trials.

 

 

This work was followed by the re-installation of the stub exhausts and other components as the work progresses towards initial running.    Oil pressure is confirmed as being good but there are some minor coolant leaks associated with the water jacket covers and baffles.   These are new components that have been fabricated to exactly the same specification and materials as the originals that were made by Sunbeam.   The originals were corroded to the extent that they could not be re-used.

 

 

 

 

The funding for this important and ambitious restoration project is progressing well and progress is being made in line with available resources.   

 

The National Motor Museum still needs help to fully recommission the Sunbeam 1000hp and is, therefore, seeking donations to allow them to return the iconic car to working order and celebrate by returning to Daytona Beach for the 100-year anniversary of Henry Segrave’s Land Speed Record on March 29th 2027.  For the museum, every contribution counts and there remains some way to go to reach the funding goals of the campaign.   Additional funding is needed to allow the car, once completed, to undertake a tour of relevant venues with which it is associated including the return to Daytona Beach to mark the centenary of Henry Segrave's 203mph record in 2027.   More information on the project and the funding campaign can be found on the museum's website below:
