On a related note I'll add that the badge marked as Babin 33-1 is not a "3 Div Sigs" cap badge nor a cap badge at all. The archival reference clearly indicates the misspelled motto was in the "collar badge".
In the CEF era, I've seen photos of two units showing use of the CSC badge. 1st Canadian Divisional Signal Company (

http://www.rcsigs.ca/index.php/File:...nuary_1919.jpg). The 1 Div Sig Coy is to be expected as it was raised from members of the CSC and members previously members were permitted to continue wearing their badges. The 3 Div Sig Coy is a bit surprising since all other Signal Companies besides the first were officially to wear Engineer badges.
In the two photos linked above, all the CSC badges on the caps are the proper large sized cap badge. I've heard of photos showing the large size collar worn as a cap, presumably due to supply issues with the proper cap badge, but I don't have a copy of such a photo. If someone does, I'd love a high quality image....
