The only thing on my Peruvian Mauser that looked messed up was the front floorplate screw - nice blue & s/n, but mangled slot. I found out why........ I am taking it apart, other screws came off fine, barrel bands took some work - were very tight, but I am getting nowhere with that one screw........... it is soaking now, but does anyone have any hints for removal ?? HELP !!!!!
