First the vehicles of the Signal Corps, which was before 1942 part of the Engineers (Genie). K.N.I.L. operated radio trucks as well as trailers. On this picture you can see both, during manouvres. The Chevrolet light truck carries the troops and tows the trailer, which has the radioroom (Stabelan).
From the same source a picture of a truck transporting telephone equipment. The signallers are posing, while some are sitting of the trailer (picture from Stabelan magazine).
Here's a real radio truck with power source in the trailer and special masts erected near the vehicle (picture from Ons Leger).
A close up of the same vehicle from the same source...
Next the pontonniers' vehicles. A regular K.N.I.L. Chevrolet carrying a pontoon section for the heaviest bridge K.N.I.L. possessed. This particular pontoon bridge could carry loads of up to 10 tons and film footage show the Vickers Light tanks crossing it while experiencing heavy waves caused by the driving of other vehicles.
The rear view of the same type of vehicle (source Ons Leger K.N.I.L. special).
This picture from Indisch MIlitair Tijdschrift shows a 1937 Ford truck crossing the K.N.I.L. pontoon bridge, full of troops. We have some reason to believe that this may be a Warford converted 6x4 Ford. Such a vehicle was tested as a possible new artillery tractor in the late 1930s by K.N.I.L.
These are 1932 GMC 6x4 trucks just bodied as ammo trucks by K.N.I.L. Arsenal at Bandung. Way in the rear the GMC artillery tractors can be seen with a different body (and high canvas cover). See the artillery tractor page for these vehicles.
A better and closer view of such a vehicle during a parade as late as 1941.
Here one more shot from Stabelan Magazine...
This convoy of vehicles shows a number of the GMC 1932 ammo trucks followed by an array of lighter vehicles, cars and autolettes/light trucks.
Later a number of Maple Leaf 4x4 trucks seems to have been converted to ammo trucks as well. One can be seen here following a sister vehicle, while towing the Krupp gun's limber.
K.N.I.L. operated a small number of wrecker trucks. We have no information on these but they seemed to have been GMC 6-wheelers. Possibly these DAF-converted 6x6 trucks have something to do with that?
K.N.I.L. Arsenal at Bandung used this not yet identified bus in the 1930s to transport its staff around the grounds (source Stabelan).
