After the war, the Dutch army had to be rebuilt and modernised, with a far higher level of motorisation. Also equipment had to be found for the expeditionary army fighting the colonial war in the Dutch East Indies, the Indonesian War of Independence. For the reconnaissance units armoured cars were taken from the various Allied army dumps present on Dutch territory, of the British Humber Mk IV, American Staghound and Canadian Otter Light Reconnaissance Car types. Though these had been obtained for scrap value in the Spring of 1946, their condition was so poor that the maintenance effort needed to keep the rusty equipment operational proved to be prohibitively expensive. To solve this problem, Humber Mk IVs had to be bought from the UK. The General Staff therefore already in June 1946 considered the question whether it then would not be cheaper to restart production of the DAF M39. For the moment it was however decided to procure the American M8 Greyhound, use the Canadian Lynx version of the Daimler Armoured Car present on the dumps and to combine the turrets of old Humber cars with the more mechanically reliable Canadian Fox Armoured Car hulls, that also could be obtained from army dumps, resulting in the so-called "Humfox" hybrid vehicle.
