I think the ambulances seen on the picture are Dodge T249 M43CDN (built on the T249 3/4-ton 4X4 chassis) on their way to service in UNEF. The Canadians had a medical detachment in UNEF-service from late in 1956 until October 1957 when the Canadian Medical Detachment and the Norwegian Medical Coy together formed the UNEF Hospital in the Canadian Camp in Rafah in the Gaza Strip. The hospital continued to be a Canadian/Norwegain joint-service to March 1959.
I finished a Master Degree about Norwegian Field Hospital's in international service (UN/NATO) last summer, and I have seen pictures of these Canadian ambulances painted in white and with UN registration numbers. The Norwegian Medical Coy / Field Hospital didn't bring any ambulances, but if they had it would probably have been WC 54's.
