I came up with a right nice blade marked Camillus,NY USN MK-2 today. It looks to have the factory edge still on it. Most of the wear seems to be scabbard wear from removal and insertion.
When did Camillus move from blade to cross-guard markings?
The reason I ask is because the sheath had a NORD # of 6581 which I read was a 1944 contract.
I guess the MK-2 and scabbard could have been coupled at any time, I was just wondering.
