David,
That is a very nice set of images of early Canadian Universal Carriers. I get a bit of a giggle out of the seat cushions placed on the left sponson bins and the convoy shot which seems to indicate that this group routinely sat that high-up in the vehicle. Nowadays the safety folk would lose their minds!
Darrell,
It appears that the “DS” on NB plates equals “Dominion Service”. Please see the paper packaging on this new set from 1972:
