The French Laffly V15T 4x4 artillery tractor was developed for the purpose of towing the 25mm Hotchkiss anti-tank cannon. Along with the usual driven main wheels, it also sported two pairs of auxilliary smaller wheels, two of them at the front, the other two midship. All these wheels, both the driven and the auxilliary ones are made from resin in our set, and in contrast to those in the kit, they are shaped as weighed.
