A lot of people are Reilly saturated. But I'm still looking for some answers about this set of barrels and have not heard anything back from the advertiser. So I'm reposting it here. Would appreciate comments about the proof marks, the barrel twist, and H&S:
A Reilly percussion gun 18 bore SxS barrel set is being offered on Gunbroker which, if it is authentic, will present a new serial number problem for Reilly's from the late 1830's-1847.
https://www.gunbroker.com/Item/1009915336The barrel has a SN 4188, which is outside of the current understanding of Reilly SN chronology. The seller claims the barrel has J.C. Reilly's name on it though this is unclear. No address looks to be on the barrel rib. And, the barrels were proofed in Birmingham. One proof looks to be post 1855 (could it have been possibly reproofed at that time?). Reilly Serial Numbered guns were rarely proofed outside of London. "H&S" are stamped on both barrels and the "Damascus" pattern looks a pretty mess.
