Wouldn't it be something to see a Clisby engine back in this one?!

That would be July 24th...

Or maybe even July 23rd.

Never on a Sunday in July '65 then? It's a Brier Thomas shot and I reckon the nose off shot above it is of the same car.

I can make out sliding spline versus tubular driveshafts in the first two cars.

Sunday would have seen that fence loaded down with people and lines of cars parked behind them. I would say Saturday would have seen more than are there in this pic, that's why I suggest it might well be Friday.

I'm surprised you haven't identified the other two Monos, James...

Not that I can this far from home, but I can certainly say that's Alton Boddenberg and his ex-Geoghegan Lotus 32 on the outside of Garrie.

The wheels got bigger?

I hope you're comparing the cars as the comparison of the pics is pretty useless. The photo of Alfie is taken way earlier than the photo of Hunnam. The photo of Millis is much nearer.

I'd love to ID 'em Ray, but it's beyond me - don't recognise the numbers or helmets. There may well a nose of a third (making a total of 4 Monos in frame with Boddenberg being the dissenter) - the one on the outside immediately behind Boddenberg appears to be a very early car still with the skinny drive shafts - so it mitigates against that particular car being Cook or Keen (and the number on the nose is not in white, so despite the skinny drive shafts, that makes it not the Millis car either - see post 162 for Millis at same meeting).

Could it be Ian Cook on the outside behind Boddenberg...

I suspect the photo was taken on practice day as the main race was run on a very wet circuit. There was a preliminary race on a drier circuit for the littlies, but it was only over five laps and this bunch doesn't represent anything mentioned in the report. I don't think Cooper ran in that race at all.

Could Keen or Millis be wearing a different hat?

Or was it simply not at that meeting?

Long shot,

Was Col Green not running a Mono around this time?

Yes, he was, Bryan...

But he's not mentioned in the race report, he's not listed on the grid. The Monos listed on the grid are:

Cook
Keen
Cooper
Millis

However, there was another race on the programme which included other cars. Not on the grid for the Gold Star event but mentioned in the minor race were:

Malcolm Aldred (Lotus)
Henk Woelders (Brabham 1100)
Brian Power (Rennmax)

Of the runners in the main race not mentioned in that report we have:

Mike Champion (Brabham) - diced with the 2.5 Lotus of McEwin in main race
Garrie Cooper (Mono)
Ian Fergusson (Lotus 27)
Alton Boddenberg (Lotus 32)
Glyn Scott (Lotus 27)

It is possible that some of these merely ran at the back of the field and weren't mentioned, but I'd think that Champion would not be one such, nor Scotty or even Cooper.

So we have a known field of:

Max Stewart (Rennmax) - 1st
Graeme Lawrence (Brabham) - 2nd
Stan Keen (Elfin Mono - but listed as a Brabham in results!) - 3rd
Clive Millis (Elfin Mono) - 4th
Henk Woelders (Brabham 1100) - 5th
Malcolm Aldred (Lotus 1100) - 6th
Ian Cook (Elfin Mono) - lapped after spin while leading
Brian Power (Rennmax) DNF

Possible other runners:

Garrie Cooper (Elfin Mono)
Alton Boddenberg (Lotus 32)
Ian Fergusson (Lotus 27)

But, frankly, I don't think they would have run. Like Scotty and Champion I would have thought they'd be saving their cars for the 99-miler later in the day.

So were there only eight cars in the other race?

The list above shows only three 1100s, but there could well have been others. A programme for the event would be a handy thing at this stage!

I suggested last night that the pic might come from another meeting, but I don't really think it's possible. I went through the entries for International races and Gold Star meetings and at each of them either Cooper or Boddenberg were not there.

So who has the list of Mono owners of 1967? Brian Lear? Streak?

For the record, that's Mike Champion in the Brabham behind Cook, who was destined to have a big spin under the bridge. Mike finished third in the race, a lap down, a very creditable effort.

I still reckon that's Champion ranging up behind Cook in post #173.

I'll have a second go at discerning who is who in the Boddenberg & co. shot a bit later. Could be Cook is rear gunner in that shot.

I would be very confident saying it was Noel Riley up on the inside behind Cooper...

Did Gricey ever run his car in a dark colour? There's something about the car on the outside behind Boddenberg that looks a lot like Grice.

The car that's barely in frame isn't an Elfin. Possibly Power's or even Stewart's Rennmax, but it's very hard to say. I'm still convinced it's not in the race.

Sorry, I don't.
I didnt really know anyone at that stage - I was just getting into Vee's and wandering around the paddock with my mouth open.
Did meet Deane socially years later, though.

James,

Purely speculative, but could that US photo have some relationship to a US driver entering the 1966 Gold Star/Australian 1.5litre Championship at Mallala - heats 3 & 4 respectively? Why I ask is that there's a "#11 P Hotchkiss (USA) Elfin Mono 1498 Blue" listed in the event programme.

In fact there's 9 Elfin Monos out of an entry list of 13.

Stephen



I've recently made contact with Phil's nephew & am now looking forward to seeing a couple of shots of Phil with the car!

I wonder whether they'll be any taken in Australia prior to taking it back to New York.

I recently took these pics of an Elfin Mono at Wanneroo Park--sorry, Barbagallo raceway:

(The car on the left is an F1000, utilising 1000cc motorcycle engines/gearboxes)

 

Unique rear upper wishbone suggests this is No 1 chassis:

Now, what was that stuff called again?

Ray the thing that I do not understand is why was the taper tube not put on the top of the shock thus lovering the center of gravity, any comments?

It's more in the windstream there.

Unsprung weight.
That design does nothing for me. Later Monos had the wishbones basically paralel with each other didn't they?

Interesting, we now have 3 reasons, wind resistance, centre of gravity & unsprung weight. So my question is out of the 3 which would be the most helpfull in the design of the car?

Remember the mk2 Mono had redesigned rear suspension & a more exposed shock assy, just wondering!

Yes, unsprung weight comes into it when you consider that he could have gone for a longer damper unit to take up that space...

 

Also overall weight. But I'm sure that when you look at how that spring is tucked in behind the end of the monocoque that Garrie saw the opportunity to cut wind resistance as the air has to squeeze between the wheel and the hull of the car, as well as flow around the suspension members and halfshaft.

 

The source of the metal piece used for the purpose is interesting, and many years later its use in a Mileage Marathon car had the heads of the boffins being scratched.
