Hiya, here is a bag from my collection.
The CWAC handbag was based upon the British ATS design, but differed in several important respects. The corners had large brown leather reinforcements and the sling had a broad leather addition to the sling to make it more comfortable to carry over the shoulder.
The colour of the canvas is also a bit more yellow in shade.
It is marked with the Canadian Broad Arrow surrounded by the letter "C" for Canada.
