Mark it is still in the white and has the long working screws. No tang screw holes even bored. Even with the fore end off it takes a lot of effort to dismount the barrels. I know loosening it a bit is part of the finishing process, I've never seen a description of how it was done. I'm guessing a bit of lapping compound or something similar. I won't need to wory about it for a long time. I still have to do the tang screws, make all the safety parts, stock it. finish the screws. make a fore end polish and black the barrels. case harden the frame and fore end iron. and probably a bunch of stuff I haven't thought of yet. Just wondering how they did it in England back in the day.
