I've recently acquired an unusual pistol. I believe it's a CVA Prospector "Bob Tingle". It's in petty rough shape, can't get the nipple out. It's soaking in Wd 40 for a few days. Any information would help. I plan on refurbishing it, shooting it, and decoraing my office with it, oh yah, and probably shooting it some more......thanks for any help.....
