Information search about Greens Cutlery Sales, U.S.A.

Recently acquired a grand daddy Barlow similar to the A.G. Russell Knife Collectors Club second year knife, but it has a marking from GREENS CUTLERY SALES U.S.A. Most likely a contract knife built by Camillus, as the Russell knife was. I’m curious about the marking though. Can anyone here please help? Thank you!
