This motor chassis & e-unit is from a 1946 model year 300 AF Atlantic. It is in good shape, and has the 1946 model year only brass buttons on it. It is in good running shape and the e-unit sequences, but every now and then, it misses a sequence, probably a new e-unit drum would fix that. The e-unit lever has just a small spot of rust on it. The wheels are in good shape. If you need this good working motor chassis & e-unit, here's your chance. I will be putting other AF parts on eBay, can combine shipping if more than one auction won.
