Egg 39 is a Brütsch Mopetta, but what is the difference to the Mopetta from Egg 6 (or the Mopetta below)?
Well, I've learned something today. I can see the obvious differences between the two Mopettas, but didn't realise the fundamental one. This is partly down to a book I have been referring to which has a chapter on Brütsch. I can take some small comfort in that the book's author doesn't know the difference between the two Mopetta models either.
The book reproduces the same picture as Egg 6, with the caption "...Also of note is the absence of any evidence of engines on the left hand side, indicating a right-hand position for the engines on these cars".
But that's obviously wrong, as the German advert posted in Reply #136 clearly says "Direct drive to the
front wheel".
So the 1956 Mopetta has the engine at the front, presumably turning with the front wheel. So Egg 39, with the different frontal design, must be a later model (1958?), with the more familiar engine mounted on the left hand side, driving the left rear wheel by a chain.
Interesting that the front-engined Mopetta was actually advertised as for road and water, but it makes it even stranger to show the later model in water. Not only would the engine have been flooded, but the whole thing would probably capsize in deep water, with the weight of the engine being on one side.
