Some of the guys here misread the initial post as RED Label. It's Gold--the short-lived sxs. Only ever produced in 12ga.

$3800 doesn't look out of line for asking prices on Gold Labels . . . not that I'd pay that much. If you're looking for a good modern boxlock for that kind of money, you should be able to find a Parker Reproduction in 12 gauge. Much better gun, and offered in various configurations.
