A slight disagreement with Musketshooter -- although I'm not familar with the barrels sold at Sarco, most new USMC Sedgely barrels were in the 1943 and 1944 barrel dates and were not used on Marine rifles. As I understand it, they went into the "mixed" for use on U.S. Army rifles, and (in a large number of cases) not used at all. I believe most of the 1941- and 1942-dated barrels were actually used on rifles. I'm not necessarily saying "yea" or "nay" on the rifle under discussion, but the 1942 barrel may be legitimate.
