Bought a lot of Vietnam Era Canadian memorabilia

Can anyone help identify this m1 Helmet? Didn't have any camo cover. Also got some pictures, a PT book and some flashlights

I'm not sure what im going to do with the pictures but I will probably sell some of the flashlights

I don't know very much but the helmet liner insert shows a US made 1986 date. I can't see the date on the liner itself.   There should be a number part way down the front brim of the helmet. It is difficult to see and is lower than you would see a US heat stamp. You can find some info about heat stamps on the internet.  I think the Canadian ones were stamped by R. J. stampings.
