I've been searching the net, and here's an earlier discussion on this subject that is on the GunBoards Jan Still site:
http://luger.gunboards.com/showthread.php?6601-Fluted-Firing-Pin!&highlight=firing%20pin
Dwight Gruber refers to John Walter's book which states that the fluted pin was instituted starting in 1934. Other discussion speculates that it was done in relation to eliminating the gas seal "step" in the chamber.
I need to see if the step is present on my Simson sn 6010.
So, the question is, were these flute cuts added during a rebuild program, and if so where might it have been done (if Simson was out of business after 1933)?
