I know many of you are experts on these, and I just cannot find much info on these (so many variations). I think this is a Bolo model, but cannot be sure. It's part of a group of pistols for sale, and out of my knowledge base. I just might buy it if I can figure out what era it may have been used. I believe it is NOT 9mm parabellum, definitely needs a cleanup. I don't know if i is commercial or military either, but I think it is post WW1. Any information would be gratefully appreciated, thanks so much!
