It's No.412 and Griffin and Howe doesn't have it in the records. I think that Fugger came to Griffin and Howe a bit later on. I have quite a few Kornbrath engraved guns and this sure matches the style and motifs of them. Eightbore, I think MP is the expert source on the Kornbrath/G&H and , for that matter, Adolph relationships. The time frame of all three, ca.1924, matches.
As an aside, probably in the 1970s, MP, engraver Sam Welch, and I had tables near each other at a small Anchorage gun show. I had a couple of Baker guns, Kornbrath engraved, on my table along with some Kornbrath paperwork. None of us really knew each other. Sam Welch came by and started talking . It turns out Kornbrath was his "hero". MP joined in and before long we had talked about Kornbrath more than I had ever heard before. Fun day. By the way, MP, I like that term, "one gun gun collection".
PhysDoc, I knew I should have a full length picture, but I am not very good at that. I will try, though, if you forgive the quality of the picture.
