Very good to know. Thank you very much for the info Now I can proceed with trying to find a replacement cylinder. I just got it yesterday at a gun show and they knew nothing about it besides it was made in Italy.. 2 of the percusion nipples were loose and would not tighten up. A friend has the same gun but in blued steel. Well, 2 of his fit in my cylinder and mine fit in his but for some reason my 2 that were in it would not get tight at all. By looking at the 2 in comparison 1 looked to be bigger threads but that doesn't tell how they were able to swap. I'd like to get a replacement cylinder in stainless but every where I've looked their sold out and cannot get. Any ideas on the 2 questions?
