I inherited a Lefever Nitro Special (Ithica Arms) 16 gauge double barrel from my grandfather in my youth. It was (and still is) fully functional, but the barrel had been cut before it was given to me do to grandpa bending the end of it. The shotgun had seen some use and was in good (but far from perfect) condition. These seem to be going for between $200 and $400 in auctions, so it's not a valuable collector's gun.
At some point many decades ago, a cousin of mine who is actually a pretty skilled amateur gunsmith refinished the entire shotgun. It can out pretty nice (Belgium blue job) but at this point, it obviously has little collector value. It sits in my safe, I haven't fired it in about 40 years, but functioned perfectly back then.
I am tempted to make a "coach gun" out of it, having the barrel professionally cut to around 20 inches, a new bead installed and the stock cut to about a 12 inch LOP. It would actually make for a very handy travel gun for when we visit relatives in NY, breaking down to fit in my travel duffel. FWIW,
Federal makes a #1 buck load in 16 gauge, which I have purchased enough for patterning and testing purposes with enough left for what ever self-defense duty the old gun might see. I suspect it would be an effective SD load at typical in-house distances.
Truly tempting, but I'd like to hear your thoughts on doing this before I send it for surgery.
