I've never owned or shot a percussion revolver but always wanted one. I found an 1860 in a local gun shop and fell in love with it. I know the owner well and he assures me that it is all correct. I'm planning to order the Colt letter when my finances recover. I've been doing a lot of reading online about the 1860's and this one seems to contradict some of the info I've read. Serial number is 85841 which should put it in early 1863. Numbers match on the frame, grip frame, trigger guard, barrel, wedge and cylinder. "H" inspector mark on frame, grip frame, trigger guard and barrel. No cartouche on grips. Hartford, CT barrel address. Four screw frame. From what I've read the four screw frame was discontinued around 50,000. I haven't seen anything that says at what serial number the NY barrel address started but I've seen many pictures on here with lower numbers that have the NY address. I'll try and post some photos tonight. Any input would be greatly appreciated. Thanks in advance.
