The markings on the .30 caliber 1895s are a bit confusing. I've seen .30-40s marked as
"30 US",
"30 Army" and
"30 US Army". The
"Govt" marking usually refers to the .30-03/06, however a member here (Boltman), has a .30-03 marked
".30 US MOD 1903.". It wouldn't surprise me if there's a couple more variations out there, every time I think I know something about Winchesters, I don't.
