U.S. Army Amphibian Jeep (Quack) Model & Video
I just picked up this U.S. Army Amphibian Jeep model (1/2″ scale). It’s dated 1943 from the Mod-Ac Manufacturing Company, LA, California. It looks complete. I’ve never run across a reference to these being called “Quacks”, but it makes sense given the larger ones are referred to as “Duks”.
Here’s a video of some “Quacks” in action during their testing dates at the Ford Rouge Plant. Lots of video shots I have never seen.
