The Jack and Heintz Co. built the Drive train for the Marman Twin! I believe that the 2 cylinder engine was part of a Drone plane project that Jack & Heintz was working on and produced for the WW2 war effort. There must of been a surplus of these engines for sale and Zeppo Marx came on to the scene and made the Marman Twin first with Jack and Heintz engine. After Marman stopped producing in 195? Jack and Heintz continued on for a couple years making a few slight improvements like adding a compression release! and running the Carter N carburetor.
This one is all original Jack & Heintz that was on eBay. The J&H came on a 24" Schwinn S-10 chassis as far as I know, and that's what this one is on!
