Hanno, David,
I know most references to the Braat overvalwagen chassis mention Chevrolets, but to check another possibility: here is one:
KNIL placed a huge order at Marmon Herrington in 1940 I believe, comprising tanks and tractors (by the way if someone has a copy or a list of stuff ordered I would appreciate a copy very much).
The tractors were mostly delivered and show up in the US mission report of August 1941: KNIL had on hand around 365 light tractors, intended for hauling AA and AT guns. According to the report they were TBS 30 type: no idea what they looked like). The guns however never arrived, so these tractors were probably used by the tank training battalions awaiting real tanks. Possibly they are visible on this well known picture (they are certainly no Vickers Utility tractors):

Anyway, also on the US mission list there is a reference to 45 medium tractors Ford/MH, intended for hauling field guns and bridging equipment. Now I was initially thinking about tracked tractors, but of course these could have been wheeled ones just as well. What vehicle could this have been?
I have never seen so far any other arty tractor or pioneer vehicle besides the Maple Leafs and Caterpillars. The field guns that KNIL tried to order after 1940 never arrived, so the tractors might have been given a different use.
Also I have never so far seen a KNIL COE truck in another role than overvalwagen.
Independently, after going through all the references I have collected of Braats, I have come to the conclusion that a total number built of 45 might come closer to the truth that 60-65.
Might these have been Ford CEO converted by MH to fwd? Vanderveen pp 347: Ford 09W/MH MM5COE for instance, used in a wide variety of functions?
Comments? please!
