The production of the tank transporter begun in 1937, although the prototype had been built already in 1932. The production variant was equipped with a longer chassis and extended cab to accommodate the tank crew as passengers and larger rear wheels than the Artillery tractor and Recovery vehicle variants. 20 ton  Pioneer TRCU20  trailer and 30 ton  Pioneer TRMU30/TRCU30  tractor and trailer combinations were delivered, in both cases with  the trailer  fixed to the tractor. Hinged ramps were used to get the tank onto the trailer, which could be pulled on with the tractor unit's winch.

Pioneer tractor/trailer combinations  remained in production throughout the war, 459 units produced in total. 

Besides many various common tyres at the time, these also often used Scotland produced  tyres we replicated in the kit with very slight angle modification for release from the mold.
