Hi Rick, of interest, this is the THIRD round of CEF patches coming out of the same place in Arizona, but being sold by at least two different names. Some thoughts. In 1917 and 1918, the Historical Section of the Canadian army overseas petitioned all Canadian Corps units for descriptions and examples of their patches. The returns were incomplete, and well into the 1920's the Historical Section was still trying to get descriptions and examples. Yet, these ladies had access to every patch, both early and late in some cases, and were able to sew them on three blankets. I too have been accumulating CEF patches for over 30 years, and I have a small accumulation. The ones I have acquired are notable for the different materials and the inconsistent sizes and variations in fabric colours. The patches coming out of Arizona are amazing in the consistency of fabric type, and colours. Likewise, some of the patches on offer are different sizes and styles than patches that have been authenticated.
I have had some of the Arizona patches in hand and they feel and smell old. Some have a really odd rubbery backing material. They pass the burn and uv tests.
The method of issuing patches during the First WW needs to be considered. After they were authorized in 1916, the Canadian Corps had many of the patches locally procured or allowed the Battalions to purchase material and indent for reimbursement. The patches were not ordnance issued until late in the war. And that was in the UK / France and Flanders. How the ladies would acquire these in Canada to sew on the blankets is an interesting question.
After examining these, it is not possible to conclusively say they are fraudulent, but neither is it possible to conclude they are authentic. Caveat emptor.
