Ed, your helmet is showing all the matching particularities of a pre-war fabrication helmet :bravo:
On most of the JR115 helmets that I have seen (no matter pre-war or war fabrication), the star was most of the time fixed much higher on the lion, so one can see clearly the lions feet. On yours and as on mine, the star is a little bit lower, so the feet are almost hidden.
Ed, does the star on your helmet also have the typical "fabrication mistake" always seen on JR115 pre-war wappen: the very small line over the word "GOTT" ? (défaut de matrice donnant l´impression d´une demi-lune au dessus du mot "GOTT").
