Guys, I sent the poster over here from Calguns because the gun puzzled me, too (not hard to do). Appeared to be a farmer-grade JABC but no Belgian proofs that I could decipher. Guess I agree that it is a British export gun using the "expired" Manton name.

One of his questions on the other board was basically what to do with it. Was advised the usual: don't shoot it until checked by a competent gunsmith who KNOWS Damascus barrels, Guage Mates, etc. And if it's off-face or has heavily pitted bores, hang it on the wall.

Some posters on the other board advised filing off the tips of the firing pins to de-activate it if it couldn't be returned to shooter status. What do you think of that?

Personally I hate destroying ANY old part because, hey, you never know what the next guy will need. If this gun is actually used for a decoration, just how likely is it that it would chamber a modern 10 guage shell--the 3 1/2" Magnums generally available to the public, not a "short 10" which are much harder for the average guy to find?
