I hear ya gunner, but this isn't a 760, it's a Savage 170 tube fed trombone. Not sure they're all too rare, they were kind of a budget gun in their day. It's a nice handy shell shucker as is, probably why I haven't sent it in yet.
LOL, 10-foe TMitch, just affirmed my no aficionado status!
cool old rifle nonetheless, I hope you bust some venison with that rifle this year.
