I don't know. The only one I can name is John Dodds "Beast", but that had the engine in front of the driver.
The thing is, I'm sure I've seen this one before it got its body on it. It's the exact same configuration (2 seat quite far apart, with the engine behind) as one I saw many years ago in 'Motor' magazine.
But I can't seem to find anything about it anywhere, so don't lock it on my account.
If someone else knows it, good luck to them!
