I just picked up a J.P. Sauer & Sohn, Suhl. Serial # 92586 12G sidelock extractor gun. It has 29-15/16 Fluid steel krupp barrels, bushed firing pins, some engraving, an Ivory bead, Matted tapered rib and it appears to be in pretty good working order, locks up tightly and cocks and fires well. The lever is very slightly left of center.
It has a few problems, cracks on the underside near the receiver in the butt-stock, below the sidelocks and some ham-handed trogloditic idiot bead blasted it and it appears that it was either caustic blued or it was painted with some type of black stove paint. I haven't figured it out yet.
I'd like to find out what model it is, when it was made, what the original finish was like and what its worth. I think it is a pre-WWII gun and was a GI Bringback.
Hopefully, I can bring it back to its' past glory and finish.
I'll try to post pictures. Pictures are posted in the "Others" album.
