Besides the twelve M39s needed in the four cavalry platoons, a platoon of three was needed for training purposes. Also a matériel reserve of ten vehicles was considered necessary. Postponing a decision about the formation of a possible full new Armoured Car Squadron, in January 1940 the ministry of defence ordered the Ordnance Department to start negotiations with DAF about the production of an additional three cars or, if a cheaper unit price could be agreed, of at once thirteen vehicles. In view of the delays with the previous production batch, armour and other components had already to be ordered. From February 1940 armour sets were ordered with Ougrée-Marhaye and Zeiss-periscopes with Nedisco. Landsverk was approached about the delivery of thirteen turrets. The Swedish company indicated that at a unit price of 9,800 guilders it could deliver four turrets late October 1940 followed by three turrets per month until January 1941. Fearing future Swedish export limitations, the Ordnance Department requested a production licence for the turrets. Landsverk refused to grant it to its rival DAF but agreed to a licence production by the Rotterdamsche Droogdok Maatschappij, that accordingly inspected a M39 in March 1940. However, DAF also made a turret design, a dummy of which was placed on the demonstrator vehicle.
