It was a Riedel flat twin two-stroke, permanently mounted I believe.
Went with the Messerschmitt Club (bubble car that is) to visit WingCo. Wallis some years back. He showed us all his collection and it included some of these engines.
Told us he'd adapted one early post war to drive a small motor boat - as you may know he was into all things speedy.
