ThunderMug H-Mod, based on Crosley, built in 1963 by Dale Tholen, originally powered by three coupled Maico engines

I forgot it was also mentioned in a certain book that I used as a source for many earlier puzzles.  

The Crosley engine came later in the cars life. Built 1960 in Culver City CA by Dale Tholen, the car had a engine that combined three, 250cc Maico single-cylinder motorcycle engines.

Don't worry, I don't have that book (whichever it may be). I was just going through tons of H-Mod pictures online.
