Hello. My father acquired this helmet as a child after WWII from a local fellow in his hometown. My grandfather served in WWII for the U.S. I need help identifying the helmet from someone with more experience. I think its either M35, 40, or 42, from the research I've done. I really cant see the marking #'s well. He tried repainting the emblem as a child. I've included some pics. Any help would be appreciated.
