The NSW Bush Fire Brigades were a prodigous user of CMP trucks in the post-war period, as were other rural fire agencies in other Australian states. The NSW BFB has recently digitised it historical bulletins on the National Library's website Trove, and you might find it interesting to scroll through some of the activities in the 50's to 70's to find pics of Blitzes in action (unfortunately, the real early editions are light on photos, but they become more illustrated as they progress):
