Canadian First World War MkI Helmet with 73rd/78th Battalion CEF insignia.  I have no history available on this helmet.  It came from an auction as is.  It is missing the chinstrap and the dome rivet/screw.  The liner is present. 

This helmet is stamped FS  173.  I have tried to photograph the insignia as best I could.   Many painted/decaled helmets are not genuine and I can not say one way or the other on this one, so please view the photos for your own determination.  I have priced it lower than an attributed authenticated FWW painted helmet. 

***I am always on the look out for collectibles (any era) to the Princess Louise Dragoon Guards for trade or purchase.*
