Here are a few pictures and link to better pictures. Its probably not uncommon but all 5 bolts have different firing pins. It also looks like there are at least two widths for these, one is 7/16" wide and 3/8" wide. All are marked with an R and punchmarks. Picture 1 compares the two bolt styles. Top bolt is from a 7/43 rifle, bottom is from an 8/43 . Picture 2 is thicker style frrom an 8/43 rifle. Picture 3 thin swept back style, early rifle 1-43. Pic 4 is R stamp that is consistant on all 5 bolts.
