Picture appears to have disappeared. That was what I thought it might be when I first saw it but upon closer inspection it was obviously 20mm guns, not .50cals. I've never seen that particular turret before (or since). Nor the manner of mounting it on a truck in that way. A most unusual find. I wonder if these vehicles were used in quantity or if they ever left Canada?
BD, there were a hell of a lot of these AA combinations tried, based upon 15cwt through 30cwt to 60cwt chassis, and all the way up to the Skink (based upon the Sherman Grizzly chassis). The bottom line is that while a number of 15cwt and 60cwt AA vehicles (with 20mm & 40mm guns respectively) ended up in continental Europe, they were mostly used for ground support and not replaced once they broke down. The Luftwaffe just wasn't the threat everyone had envisioned. Most of the odd-ball pics you'll see of AA trucks are one-off test vehicles which never left Canada... I suspect most were converted back to GS trucks at some point in their lives, and there are but a handful left in existence.
Interestingly, the one REALLY oddball vehicle was an adapted 2pdr carrier, which unlike the Australian example, was of almost identical layout to the standard Universal. We made 24 of them only, of which one was sent to England for trials and seven or eight survive here. Pretty amazing percentage when you think about it!
