Vintage Scale Models Minneapolis Moline UDLX Toy Comfort Tractor NIB 1/16 & 1/64 Scale. This set is pre-owned and appears to have not been removed from the original box. Included in this set is a 1:64 scale UDLX toy tractor as well. The Minneapolis Moline UDLX tractors were built in 1938 and were ahead of their time in features but only about 125 were built. Other features included a radio, heater, defroster and windshield wiper. They were billed as a tractor that you could work in all day and then take it to town in the evening. Why not add this beautiful set to your collection today? This would display well with most vintage 1:16 scale farm implements.
