On 10 and 17 December 1930 Brandt had obtained an order for six complete sets: tractor, trailer and tractor-carrying trailer. To honour its commitments to Vickers, it let the trailers and one tractor be built in Britain. To conform to the idea of production in France, Brandt delegated the task to build a new tractor type to the Latil company, as it had too little experience itself. The Latil prototype, presented on 7 August 1931 was very much on lines of the British type and strongly resembled the later Universal Carrier: fully tracked and with most of the vehicle covered by an open rectangular superstructure to ensure as large a carrying capacity as possible. Only a small driver's and engine section on the front was armoured on top. On 17 July the commission considered the type ready for troop trials.
