By November all turrets had been delivered by Landsverk. However, they had not yet been fitted with any armament because the Ordnance Department had decided to produce the needed 37 mm cannon itself in its arsenal, under a licence obtained from Bofors in June 1937 to equip the earlier M38, and manufacture had met with some serious delays. When the first car was officially delivered by DAF on 27 November 1939, not only did the turret lack any guns but also the hull machine guns and all visors were absent. Nine vehicles, also in an unfinished state, were delivered in December and the final two on 3 and 5 January 1940 respectively. DAF reduced the price by 1500 guilders per unit to partly compensate for the deficiencies. The cars were moved to an Ordnance Department facility in Delft to be completed. In late January the first vehicle could be fitted with the first 37 mm gun produced for the series and at the same time equipped with a full set of episcopes and periscopes provided by the "Nederlandsche Instrumenten Compagnie" (Nedisco); it was immediately tested at the gunnery range at Oldebroek. In February, five other vehicles were parked at the Cavalry Depot, officially "fit for military use" but in fact still waiting to be equipped with guns.
