The Heritage Trust does have quite a large amount of material on the development of this engine, glean from kind donations from the estates of Tony Crook, Dudley Hobbs, Dennis Sevier as well as our purchases from the sad Windlesham bankruptcy.
There's more articles, or probably a whole book in this; much of our hitherto unseen material (currently locked down in the city of Bristol archive) will repay serious research.
Among our acquisitions are; descriptions of both versions of the all-new engines, the 3 L version, and what was eventually the 3.65 L, photographs of wooden mockups and also of the engine itself, Original watercolour artworks showing a variety of exotic coachwork built on this car, an interview with Alex Moulton describing the prototype test car for which he had made the all rubber suspension,(see our website for this interview) two wooden models of possible coachwork versions, engineers report on a test to destruction of the engine, accounts with various costs, and sundry correspondence yet to be sorted.
All will be revealed in due course when we can get round to it. The 3.65 engine would've put Bristol on a par with its rivals Aston Martin, Ferrari and the (much cheaper) Jaguar.
The quality of design and construction are evident and IMHO far above the competitors I have mentioned. It would've been a Maserati eater. Ahhh, what might have been…
We are still negotiating for the remainder of the Bristol Cars Ltd plans and drawings and have undertaken to beat any genuine bid. Watch this space and wish us luck.
