Thank you all again for your responses. My son will be around this weekend to help me move the accumulated pile of stuff (not at all "more junk" like someone else in my house seems to call it) currently blocking access to my gun safe. Then I can post pics of it. If memory serves though it is chromed / nickled, .32 rimfire, with yellowed grips (perhaps ivory?), and it does have rounded butt. I ordered and received a hand full of rimfire adapters that allow you to insert a primed empty. 22 short into a hole in the outer rim of the adapter cartridge. Then fill with blackpowder and seat a .32 (yes I know it's got a 3 digit diameter - I just can't remember it at this time) cast round ball in and link away. I don't want to start a debate over whether it'll pull the balls in the other chambers etc etc. It works, and it's fun to shoot it. Just have to clean attentively afterwards. I'll post the pics asap.
