These articulating steer 8x8 amphibious ATVs were made by American Machine Foundry company in York, PA. I always had a fascination with them and I got to see one in person today. It is quite a machine! Its powered by a 297 JLO single in the rear half of the ATV. Imagine what some 22" Rawhides and a big 29HP liquid cooled Kawasaki four stroke could do for this machine! If anyone else has any other info on these machines please post it up!
