Looks quite neat. I wonder on the cost though?
A similar, if perhaps not quite as detailed tractor, in 1/48th scale, is included in the Academy ground equipment kit, and in the Revell/Promodeller Ground Support kit, which can still be found, and will probably be re-released at some point. It's also available with the Tamiya Corsair kit.
Would be nice to see it in 1/32nd scale though, and will certainly be welcome to 1/72nd scale modellers.
We could really do with a lot more in the way of vehicles, in all the three main scales, for airfield/aviation, and at last, Tamiya are about to release their US 6x6 fuel truck.
