We worked directly under The Department of Defense, Tank Automotive Command. It is a Tracked Vehicle Rebuild Center, which also has a large Small Arms Rebuild Shop, and a large Ammo Storage Area. In 1977 after 4 years in the Army, I was fortunate to get a Civil Service job at Anniston Army Depot.
Now for the backstory on the print or etch on the blades. Although the knife is in great shape, the print is weak. I have one that is an Ulster 3-7/8' Trapper.
