Pavesi P4 Artillery Tractor

I am perfectly aware I am rather off-topic with this picture, as the Italian artillery tractor Pavesi P4 was used by the Italian Regio Esercito between 1927 and 1942, but this incredible vehicle is based on a civilian version (built for farmers) developed in 1918.

As you can clearly see on this picture shot in Militalia military show last week-end, this vehicle is based on two separate chassis, in order to increase its four-wheel drive capacities. This artillery tractor was tested by several countries, including British Army.
