Your AoS and unit serial are exceptional, most likely better painted than even those found on the vehicles of the time. Keep in mind that your vehicle markings are placed correctly for 4 Brigade in Germany for the period up to the early 1960s but are reversed (vehicle rear only) for Canada. Also Mobile Command replaced 1st Canadian Division in Canada in about 1967ish. And finally CFR plates were not introduced until 1970-71 and yours is one of the latter kind with embossed CANADA which dates from the late 1970s - after the M37CDN had been replaced by the Chevrolet 5/4 ton. Prior to 1970 DND vehicles were plated provincially and no plates were used in Germany.
