From what I can gather, having only been around this world a short time, the American commercial knife world is highly incestuous. For instance, Queen produces knives under several different names, produces knives for other companies, and other companies produce knives for Queen. Names get bought and sold, sometimes overseas, and yes, it can be very difficult keeping track of who makes what and where it's made.
I think the GEC brands are just an extension of that. They owned (or bought) the names to a few old US brands, and are now producing knives under those names, likely in the patterns that were originally made by those companies.
