I have now finally found my records on this car, and I am delighted to confirm to PJ that actually your AWR answer is correct! The car I was thinking of from memory was the AWE! (another British 1930s-style roadster kit car).
The full correct name of this car is the A.W.R. Roadster Special, built by Alf Richards. The A.W.R. was intended for production, and was displayed at the Stoneleigh Kit Car show in the 1980s. However, despite the high construction and engineering standards, no customer orders were ever placed for the Roadster, so it still remains a one-off.
Alf Richards went on to convert Range Rovers and Toyota Land Cruisers to six-wheel-drive, with BMW V12 engines! Today he is still very active, converting VW and PSA MPVs/Mini Vans for disabled use to carry wheel chairs.
So, another BH long-termer bites the dust! Well done PJ (with a little help from Steve Hole
).
