I once had a Winchester 1873 rifle (not carbine) in .32-20. Externally not great but OK, fair wood, and everything worked, however the bore was heavily rusted. I considered having the barrel bored and sleeved, as there was a gunsmith in a nearby town which did such work. But (this being back in the early 1980s) it would have cost me about $150 for him to do that. I didn't pay much more than that for the gun, so I just sold it for about what I had in it. Another one of my numerous gun blunders.
