This is an Italian Vender tractor of the early 1950's. It's in amazingly good condition, and obviously hasn't done a lot of work. I guess you wouldn't want to wear it out - Vender disappeared as a crawler manufacturing company in 1962 - and any parts you needed nowadays, you'd have to make. Vender commenced production of crawler tractors during WW2, was later nationalised as a Italian Govt-owned business - but ceased production in 1962 after incurring heavy losses due to poor management, poor quality products, and poor sales. They had some wonderful tractor model names such as Vender "Destroyer", Vender "Champion", and Vender "Bully". Unfortunately, their products never lived up to their wonderful names. The engines were Venders own design, and you'll also probably notice the twin-cylinder, horizontally-opposed, starting engine, a-la Caterpillar.
