Anyone here old enough to have worked with the "Snowmobile, Armoured, Canadian, Mk. I"?
"One notable Canadian-designed and produced vehicle that arrived for field tests was the Snowmobile, Armoured, Canadian, Mark I, often referred to as the Mudcat, and later known as the Penguin. This remarkable little vehicle was designed as an armoured, two-man recce vehicle for cold weather regions. This vehicle was the result of a verbal request by the British Ministry of Supply, and was a development of a full-tracked unarmoured snowmobile, upon which the Army Engineering Design Branch had already conducted tests in 1943.
Equipped with a Cadillac V8 engine coupled to a Hydra-matic automatic transmission, and a Ford T16 Universal carrier axle with controlled differential steering, this vehicle was tested by the 5th Armoured Brigade in the first weeks of January 1945, when it was issued with one M29 Weasel and 12 snowmobiles. With its armoured hull and ground pressure of only 1.9 pounds per square inch, it not only provided good fun for the Strathcona's recce troop but proved able to negotiate all types of mud, sand and snow encountered. It was compared against the M29 Weasel and the conclusions reached were that the Weasel was fine for carrying stores but not useful for much else because of its lack of armour, very short track life, and low horsepower-per-ton ratio of 10.9, compared to the Canadian snowmobile's 29 hp/ton. The Penguin proved to be an ideal recce vehicle, with provision for a No. 19 wireless set, a Sten gun, a rifle and a Bren gun that could be mounted on any of three pivots on the hull front and sides. It was also tested for bringing forward supplies to areas previously accessible only by foot or mule, and six-pounder guns were towed through mud up to the axles with no problems.
For added load-carrying capabilities, two trailers were designed in the Mediterranean theatre for use with the snowmobile. One, designed at the Mechanical Experimental Establishment in Cairo, was based on the tracks and suspension from a Universal carrier and was quite serviceable. The other was designed in Italy and was found to sink in soft ground. The British discovered that while the vehicle was being tested in Egypt of all places, it overheated when operating in temperatures above 70 degrees F - a fact that was confirmed when the instruction book finally arrived. In all, 415 of these nimble little vehicles were made. Of these, three were shipped to Russia, 400 were ordered by the British, 10 by the Department of National Defence, and two Mark Is were supplied to the Army Engineering Design Branch. Orders were placed for a Mark II version with improved cooling and better weather protection for all-weather use. Unfortunately, this was after the major component assemblies were already out of production. This necessitated a cutback of four vehicles to the British order, under Contract #UN 4718. The fifth vehicle came under Canadian Contract #MP 10027. Therefore, the total production was 410 Mark Is and five Mark IIs. They were not taken on strength by Canadian units as there was no requirement for them in Canadian units and spring was approaching."
