3D Printed Kit. The Laffly S-45T was designed as a 6x6 heavy artillery tractor for towing heavy guns such as the 220mm Schneider as well as for recovering heavy tanks. The S-45T was powered by a 6.3litre 4 cylinder engine capable of 110HP and could carry a payload of 2tons. However, only 17 were ever produced from 1940 so their role was also fulfilled by S-35T tractors. Captured S-45T were also used in Wehrmacht service.
