Here is pre ww2 helmet used during ww2 that was the same steel body as the WW1 M1917 helmet shell except the liner system had been completely revamped. I have my M1917 helmet up on the imperial WW1 part of this forum if you want to compare the differences. This particular helmet is stamped 23A and was made by McCord (correct me if I am wrong guys). These helmets were made from 1936 up until 1941 at which point the M1 was put into production. It has the early war brass buckle with bar and sharp J hook (we all like to see these on our early M1s ) the leather liner is well worn through with use and the padding that would have been on the inside dome is missing this is a used and abused lid. Please feel free to add anything and thanks for looking.
