Outstanding, guys. I logged off for a few hours and all my questions were answered, even one I wasn't smart enough to ask. You nailed it on the Sight Corrector. The picture is exactly the same as mine, except the plate has been broken off. Are chopper lump barrels rare on damascus? I don't see a joint line on the lumps, except for perhaps a half line on the front lump from the 4 back. I have attached a picture with the extractors off. It doesn't show much more but it is all I have right now. There is a piece dovetailed into the lug closest to the muzzle that is difficult to see from the top angle. Would that be original or a repair? I'll try to get better pictures and post them. Thanks again for all your help.
