Hi Everyone here is my other purchase, hopefully better luck here. It was marked as a 1865 gentleman's pistol. It has a rifled barrel about 0.55 Inch caliber. here are some pics, it has some maker marks on the barrel (can see in pic).
It's a VERY nice find, but missing the ramrod, and the other one of the pair. This/these were a pair of gentleman's travelling pistols that may also have doubles up as target pistols, judging by the fine sights and what appears to be a set trigger.
Here in UK we would shoot that in a target pistol competition, having had it checked over by a competent gunsmith, of course.
Timewise, I'd put it at the beginning of the percussion era, around the 1840's, as the style is certainly not that of the 1860s - it is far too ornate and far too much physical resemblance to its flintlock predecessor. Here in Europe, by the 1860's, the railways had taken over 99% of all horse-drawn stage-coach travel, by then a hopelessly outdated anachronism along with the need to protect oneself from brigands and 'men of the road'.
