madcratebuilder,
I found mine at a local gunswap show. It had never been shot, but it had a cylinder ring gouged in it from people playing with it. It was in the torn up box with no papers. No one there was into BP and the guy wanted $175.oo, but I talked him down to $150.00. I actually did not know what I had either. It just had beautiful grips and a pretty blue. The only distractor to the gun was the cylinder ring and tarnished trigger guard. I really bought it for a cheap reenactment gun.
Once I get it home under the lights I noticed the dovetailed front sight and the smooth action. After asking some questions on the internet, I was told to look down the barrel and see if it had progressive rifling. That, and an email to Navy Arms sonfirmed the gun. It's just a once in a great while lucky finds for me. I usally end up loosing on most deals.
I shoot it now, have put simulated ivory grips on it, cleaned the tarnish off the silver, and have decided to have the gun "authentically" converted to cartridge. It will make a great addition to my reeanctment character and provide some flash and shine to my gunbelt.
