Found this document on equipment being offered to NATO allies under the Canadian Mutual Aid Programme in 1955.
The list includes a total of 580 of "Trailer, 20-cwt, 2-wh, GS" being offered to Denmark, France, Italy, Norway, Portgal and Turkey. As far as I know, Norway was the only country to take up this offer, totalling 65.
