I picked this lock up a while back, and while it’s not really considered an antique, It’s odd ball enough to peak my interest, so I bought it and decided to share it with you all. Enjoy🙁nerd):
The seller said that someone ingraved their name on it, but after looking at it closely under a microscope it looks to uniform to have been done by hand and I believe it was factory applied. The reverse side has a circle with the initials Bte SGDG and V.P.X. Maybe someone knows what it stands for. Mark
