During WWII Springfield got a couple of the new GermanMG-42 machine guns and tried to reverse engineer it... and failed. It ain't so easy!
BTW, GCAjust got a Letter to the Editor from a member: "... about 1976 Sumner's Hardware in Ft. Knox, KY received a large group of guns from an estate. I remember examining a Japanese
Garand
. I didn't buy it and have regretted it for the rest of my life. I think it was $125. It was it sad shape. The action was jammed, the stock damaged, and the magazine box was missing. I didn't know what a treasure it really was. Lost opportunity."
