December 1935, but by this time he had designed a lighter tank platform that had been taken up as the A10, although later known as the Cruiser Mk I. In this version, one large wheel was fitted on one bell crank, and two smaller wheels to a shared arm on the second crank. This went into production in 1937 as an interim type until the Army could develop a tank using the Christie suspension. The same suspension was then used on the larger Cruiser Mk II which came to its ultimate form as the Valentine tank. A further variation on the basic concept was introduced as part of various light tank projects, notably the Light Tank Mk III of 1932 which saw use in Egypt. This version was essentially a two-wheel variation of the design for the A10. This variation was then found on a huge variety of following designs including the Universal Carrier of 1934, and the variations on that design like the Loyd Carrier. In 1943, a single Ram tank, a Canadian-built version of the M4 Sherman, was modified to trial Horstmann type suspension. This used two full bell cranks like the earliest designs, but moved the shock absorbers to the lower side of the wheels. Although this was highly successful, running over in testing, the Ram was cancelled in favour of purchasing US-built M4s and turning Canadian production to other designs. A single Sherman V, serial T-148350, was then converted in a similar fashion. This proved successful in terms of ride quality, but unreliable in testing. By this time the US Army was testing a huge variety of new suspension concepts, eventually choosing one of these for the late-war M4E8 models. The single Horstman Sherman ran before the project was cancelled in 1945. As the war wound down, the British Army was deep in the development of their first "universal tank", which would combine the armour of a heavy tank with the mobility of a medium. This was originally to use a Christie-type suspension, but as the design continued to grow in power and weight this had to be abandoned. In its place, Associated Equipment Company designer G.J. Rackham came up with a modification of the Horstman able to support the larger frame. This was essentially identical to the original two-bell system, but had three coil springs, one inside the other, to give it the required weight
