Good morning gents I have had this M1 in my collection for some time and the old girl is a little on the rough side but I still like her as it was the first I added to my collection some years ago.
I do believe it to be a post war helmet as it is it is devoid of any heat stamp or any other kindof markings that I can find any were it is a rear seam swivel bale and IMO it has been repainted at least once in her life as you can still see the rough sand texture poking through in a few spots.
I do know that for a period of time there were M1 helmets produced in Canada so I am curious if this could be one of the Canadian produced Lids.
I was under the assumption that the rims were manufactured from stainless steel on the Canadian produced models though and still had a heat stamp number of sorts
