Hello Kuno,
Always nice to come across a derelict CMP. I had the pleasure to run across one on the isle of Crete some 25 years ago - see
http://mapleleafup.net/vehicles/wrecks/wreck_03.html. I understand it still survives as a derelict, so they can last for a long time.
The one you spotted has survived as it was used by a farmer after its military service. It must have been retrofitted with another, longer engine - most likely a diesel. Hence the "nose job" conversion. The wheels are not the standard military divided rims, and it has been fitted with more substantial side windows. The cargo box has been lengthened and a pipe framework (likely made from the original "hoop sticks") added to increase the loading capacity.
As far as I can tell this was originally a Ford F15A 15-cwt 4x4 truck, judging by the tight radius on the nose cone an the rear view mirror mount (both redlined in the attached photo).
