Someone here knows.... I'll throw out a guess or two.. Colonial..........Ideal..........Imperial..........Novelty Knife Co.

According to Blade's Guide to Knives and Their Values knives with USA on the tang and plastic handles and upset steel bolsters were usually made by Colonial. Those with bone handles and steel mounts were made by Kingston for the US Army.

I'm thinking Colonial on that one.
