USMC on (S) barrel means United Shoe Manufacture Co.?!

[Jim Tarleton]

Sedgley contracted with Winchester (and maybe others) to make barrels for the Marines. The USMC on the Sedgley barrel stands for "United States Marine Corps" and there should be a "S" in a circle also. Most of the ones mounted by the Marines will have a 1941 date.

The shoe company didn't really need the barrels:-).
