Wonder if any one is printing this out. The one in the B24 kit is really basic.
There is a 1/48 kit from Ot Vinta!. A link to a build review of the kit, OT VINTA M2 Cletrac. It may be difficult to get because it is from Russia.
I did find a 3D model of one you can download and print your own, for a mere $159.00.
There was one from Viking Models (evilBay seller Pathfinder 44) printed in various scales but... not seen. As for the Russian one, good luck getting that resin kit! Note, the builder mentioned a lot of warped parts and the need to add his own details.
Viking Models one piece 3D printed tractor.
The frugal way is to update the tractor from a monogram B-24 kit. Click image to see build including fuel trailer from ancient kit...
