Some background. There are four Ac Aceca Brooklands as follows:
Car No.1 - This aceca, which is a late Ac Ace Brooklands with a stretched chassis. That is why the headlamps are square and the rear is based on the Aceca Buck (which I have in storage). The chassis was not the same as the next three which are fully designed specially for the Aceca design. The late Ac Ace Brooklands is sometimes called "South African Cars". There are a small number out there, I know of 8 cars, but expect 10 just documenting the ones I have found.
Car No.2 / No. 3 - This was the production version of the car, I have one of the cars and Steve Gray has the other. Both variants are chassis's specific for Aceca and the buck, body has now changed with the sweeping front end, etc.
Car No.4 - The last chassis built, not completed. This is a full chassis like car No.2 and No.3 but never finished. I have all the parts to build the car including all bucks. Not sure if this will ever occur. But you never know.
Anyway, thought it would be worth putting some extra detail down. I have updated the register now to define a lot more detail. Plan in the new year to produce updated version for action.
