Here is my latest M1 ( arrived yesterday)
The liner is Firestone, with the A steel washers,and head band spring clips painted Olive drab. c 1943-1944, I believe.
Quite chuffed as this is the first lid I have bought that's 90% complete, therefore the nape strap is a bonus feature to me.
The lid it's self has no chinstrap's, which is a bummer, but I will look through my box of spares and see what I got!
It appears to have some sort of rank / marking on the front,which is silver in colour. This one is unusual to me at least, in that the bales are only temp attached, (only welded on the Middle part,the outside weld's were not attatched as far as i can work out) and has a weld spot/dimple opposite the bales,on the stainless rim.
Enjoy ,any comments, observations or any more info would be great , cheers Guy's.
