i found this info, about the schrade 752.
This is a Schrade made especially for the NC Textile Industry in the 30's-70's. This one says Carter Traveler Company; Gastonia, NC on one side of the aluminum handle and Mill Devices Company; Knotters on the other. A Traveler is the piece of a loom that carries the thread back and forth to weave the cloth. This knife was a give away by the equipment supplier. about 3-1/4" closed and 6" open. Single blade. A true collectors item in like new shape.
hope this helps
