Without making any cultural criticisms, I was told the average Canadian soldier in WWII was a bigger man that his British peer. Perhaps better childhood nutrition and health. I would expect the same might be said for the ANZACs.
Ed Storey organized a ceremonial parade in battledress using clothing on the racks from one program or another at the Canadian War Museum. He has his own uniform, but me and another fellow who were typical Right Marker candidates were struggling to find the largest and tallest tunics and trousers on the rack. Mine had Pay Corps Captain's rank, and my puttees were barely gripping the cuffs.
(Show of hands, how many MLU'ers know how to wrap puttees?)
