I'm not convinced these are Canadian. Could someone make the photo larger/more detailed? I'm not sure these are Canadian issue helmets. I also think Candians had a shoulder patch "Canada". If the source is from the Australian War Memorial, it would suggest otherwise. Thanks

Thanks very much. Very interesting.  Always nice to see and learn.
