Ok guys, here’s what I have. I Remington 44-caliber Model New Army made during the Civil War. Correct Brass trigger guard, Stylized “GP” marking in small rectangle box on chipped grip panel which are the initials of Giles Porter, a Principal Sub-Inspector for the US Ordnance Department.
Under the barrel on the flat there are the markings 85504 CSA in a staggered strip as well as the same markings on the frame under the left grip panel.
There are no Barrel markings on the side of the barrel and it may have either been refinished or possibly not stamped at all as the barrel marking on the flat underside is still crisp and readable.
I have seen no other Remington New Army’s marked CSA anywhere and I ask the forum two questions;
1. – Could this be an act captured US Army weapon that was turned around and used by the Confederacy with CSA markings?
2. Could the markings instead have instead been placed post-war by a surplus seller such as Bannermans (which was known to place CSA markings on civil war era weapons to increase the value)
Any information or guidance anyone can give me would be appreciated.
