Gil;
Look forward to seeing pictures of that one. I took a look at some of mine today.
The one I have looks just like your BGI with reversible pins. On the crimp head, it is marked "Reversible Pins for Square or Round Crimp 10" & then on another line very faintly B G I Co Pat Sept 1891 or possibly Sep 1, 1891, hard to say for certain. I believe it is identical to yours. This is actually the best crimper I have. As I said I made a 12 ga head for it but didn't make reversible pins. I just drove in roll pins & put the split on the back so a rounded side would make the crimp. Had to also make the inner sleeve which puts pressure on the top wad while crimping.
My boxed set is marked Eureka. The box is in bad condition but appears to have been made by Freeport Guin & Implement co, Bridgeport Conn.
