From what I can gather, it was accepted as part of the February 1864 shipment.
The numbers on the frame, barrel, cylinder and triggerguard match, and the cartouche is present although faint.
The spring on the hand is broken, and it seems that someone took it apart at some time to see if they could fix it, and in the process the trigger, bolt, and some other internal parts have been lost to history.
I have the parts on order, and will see if I can get it back together; even if I never fire it, I would like it to operate properly.
I don't see any signs that the gun has been worked on (other than dings/nicks from disassembly), but the stamp on top of the barrel is very faint. I haven't seen many of these, so wondering if that is common?
I've attached some photos, so any input is welcome.
