The car is a replica of a late 1968/69 Brabham. - see picture
I am not expert in BT numbers, but the car's body is identical to the beautiful Brabham that Bib Stillwell raced in historic racing in his latter years.
The history, as related to me, from the previous owner, is as follows:
A RAAF aeronautical engineer in NSW constructed 2 cars, commencing in 1968, based on the Brabhams of the period. - hence the name Orion ala RAAF aircraft.
I am not sure about the chassis, but whoever made the fibreglass body, must have had access to a Brabham, as the moulds are visually correct.
The cars were not completed until 1972 and my car was raced first with a 1400cc Renault and then with a crossflow Ford 1500cc.
The car is now fitted with a 1400cc Renault engine which I have rebuilt, but the car still has evidence of the Ford's engine mountings and it came with a beautiful extractor/exhaust for a crossflow Ford.
The gearbox/transaxle is an up-turned 4 speed Renault R 10 (?)
Front uprights, in the best tradition, are Triumph Herald, with what I am told, are Renault, floating caliper brakes. The rear has rather agricultural fabricated uprights with what, I am advised, are Mini Cooper S brakes.
The logbook shows the car raced at Amaroo in 1972 but was never, (hardly ever), raced thereafter.
The CMS, C of D which i obtained, unfortunately classifies the car a Group Pand Q which means. although it is, in intent appearance and feel M and O, it must compete against the F5000's and Atlantics.
I would appreciate any advice, information, stories etc about my car as i intend to carry out a rolling restoration.
