Very pleased with this M1915 Prussian e.m's pickelhaube from ebay which has arrived today. It was extremely dusty before I wiped it over and strikes me as totally untouched (though I have added a repro chinstrap). The liner is fragile but the outside is very good. I especially like these wartime produced pieces with the removable spike. Any comments welcome, and please let me know the meaning of the ink stamp if possible.
