So, this is not my usual avenue, but can anyone tell me more than I already know? Perhaps I’ve missed something…..

This is, I believe a late 1943 helmet complete with high pressure liner manufactured by The seaman paper company. In 1943 the fixed bale was replaced in favour of the swivel bale, Up until late 1943 the rim of the helmet was stainless steel with its join at the front. You can clearly see the front seam and the S letter on the liner. It has the letter “S” stencilled in black to the front. And seeing as this is not my cup of tea, I will bow to greater knowledge…….. The liner has blue paint traces all over….Navy?

Thanks
