My latest purchase is this Bavarian M.15 Mannschaftshelm the quality is stil very nice it has no regiment markings but inside the helmet there is a maker stamp (Kleinhem ? 1916) and a other stamp that i dont recognize it look like a big S enjoy the pics.
I have a s53 Baden M15 which is similar in (pristine/unissued) condition... I love it except for the tiny size. I would've preferred it to be at least s55 so that is displays better...
