Good morning Mark!
Thanks for your help.
Since last night when I post pictures of my helmet on different forum and collector's pages, I received always the same comments:'' It's the first time we saw a helmet like this with a flash on the side.''
It's important for me to support my collection with historical document. So if you can provide me a picture of a member of the Sherbrooks Fusiliers with a helmet with a flash on it, that will be great!
