BILL,
The third photograph with the two stag grips are as follows:
The one on the left has some kind of blurred stamped trade mark that I cannot make out and the one on the right has no trade mark. The blade is very bright and the etching is deep and clear.
The 4 th photograph shows the one on the left with the skinning knife to have the old WKC stamped logo with two figures on it. The skinning knife has an etched blade.
The one on the right has a lighter weight to it. It is well stamped with a heavy squirrel Eickhorn logo.

Sincerely,
HUBERTUS
