Working in the brim some more. I will definetly have some folds, but I hope to minimize this when I’m done. So I plan on washing the fabric in warm water then putting it in the oven at about 100 degrees so it can dry at a hot heat which will shrink it to the helmet. Hopefully…

I bought his book from him at the SOS. Very nice guy.  Rest in Peace.

I have been collecting for several decades and had the same question myself.  I looked it up a few month ago.  Collectors have sometimes considered it an "acceptance" stamp proving that the piece of equipment had passed the final inspection....ready for service.  It is an ordnance mark and is often found on uniforms, hats and the like of those involved with the US ARMY ORDNANCE CORPS.  in modern times, i.e. 20th century, the symbol found on rifles and bayonets simply represents (as stated on google)  " the Corps' historical and ongoing role in the development, maintenance, and supply of military weapons and ammunition."  The US army's first use was in 1832.

I had thought about that. There doesn’t appear to be any marks where a bayonet lug had been taken off.

Another possibility is that it did receive the post-war upgrades and was put into a M2 stock, then someone got it and "restored" it to its original configuration.  Not hard to do, and a correct stock may have been more than the person who "restored" it wanted to spend at the moment.
