My own favorites aren't doublegun felonies, but common misdemeanors anyway. I have a Colt New Service .45 LC that is near mint except that someone cut the (originally 7 1/2") barrel off to 2 1/2" and installed a Williams Shorty Ramp with gold bead. Shoots OK but what a waste!
I once tried to talk a "gunsmith" out of pulling the barrel from an original Win Hi-Wall 1885 .30-40 because it was "shot out". Actually it had about 1" of roughness in the grooves just in front of the chamber--really "frosting" not pits. He pulled it anyway and gave it to me and replaced it with a cut-off, re-threaded, and rechambered 2-groove Springfield barrel. Instant abortion "WinSpringKrabean." The good news is, I saved the Krag barrel and put it on an orphaned Hi-Wall action (yes, you could find those about 40 years ago) and have been shooting the heck out of it ever since; one of my favorite rifles. I guess the moral is "SHOOT it before you "FIX" it".....
