Toss-up between my Nepal-made P-1853 Enfield rifle-musket (bought from IMA a few years ago, in uncleaned condition, and once cleaned up it was still shootable!), and my Smith & Wesson Model 2 Army, which was made in 1864, and bought from a company called "Campsite Artifacts", or something like that. The S&W was refinished at some point in its history, and the cylinder number does not match the frame number, but it is tight, has a good bore, and is mechanically sound.
