Sorry, my misunderstanding. That picture does help.
That mark/brand is not listed in Goins' Encyclopedia of markings. So, at the risk of being 0 for 2 (
), I'll SPECULATE that these were a special factory order done for one of the smaller guys. Sorta like a smaller version of Frank Buster and his Fight'n Roosters. Probably done on contract by one of the German companies like Olbertz, Schlieper, or Robert Klaas (who does use a similar small circular shield on some Kissing Cranes).
With that said...My search of the Internet was not fruitful, so I really didn't help much in locating any "Red Stags" for you.
Sorry. Is Goodwin still in the business? Maybe at one of the area knife shows?
