First one is a Canadian Lamp Company made one, from 1942. Liner is clearly marked 7 3/4 VMC I 1941. Helmet is in nearly mint state. I added the net and the scrim. Not too sure about the screw.
Second is a General Steel Wares one, made in 1942. Has a net and a Canadian made (Johnson & Johnson 1943) dressing under the net. Net looks like it has been on there for quite a while.
Liner marked 7 1/8 but in a difficult place.
Question is what a fair price for these helmets is.
