well, I'm trying to expand my realm of collecting, and came across this helmet in an antique store, all the marks on it look right. it was made in Canada, in 1940 due to the G.S.W. makers mark. the batch letter looks to be a "B." I was planning on putting an original liner in it along with a chin strap. what do you guys think? I'm a collector of German items, so im not to knowledgeable of the allied militaria.
