Got a couple of questions for you folks who have a really late CYQ P38. I'm looking at purchasing an a prefix pistol, near mint conditon, all matching. One question is the locking block under the barrel. It is matching numbers, but is blued instead of polished bright like the AC/BYF pistol blocks that I've seen. Also the finish to the frame is very rough. Does anyone have any comments about what an a prefix cyq should look like in terms of finish, locking block, etc?
