Early May 1939 the contract was signed for twelve units of the "P.T.3" or "M.39", to be delivered before 15 December 1939. DAF would only manufacture the hulls but also be responsible for the final assembly, using turrets to be delivered by Landsverk and armament to be supplied by the Ordnance Department. By 1 August, 16 September, 7 October and 1 November 1939 respectively three turrets each had to be made available. The intended delivery dates were: the first car on 15 September, the next two on 10 October, three on 1 November, three more on 23 November and the final three on 15 December 1939. The total price was 529,600 guilders; the prototype was to be delivered by 15 December at the latest, and for free.
