Attached are a few pics of my Edwinson Green pinfire, Serial #65.

I know that he was a respected english maker, but does anyone know a little more about him that would help my judge the quality of this gun. From what little I've been able to figure out, it's mid 1860s or so. I WISH I had a pic of the barrel stamps, but I can take some if anyone has an interest. Lastly, if anyone knows a source for pinfire ammo, I'd appreciate it. When I bought it I thought it'd make a cool centerfire conversion gun, but I can't bring myself to have someone attempt that. I do recall the barrels are proofed for 3 dr 1 1/8 oz loads, which surprised me. Thanks.
