My father has had one since 1965 ish. He bought it new. It's not his main tractor any more but it's still a workhorse. He swapped out the 12 HP engine for a 18 HP dual cylinder model about ten years ago. We had to do some mods to the frame, hood and front grill to make it fit. I see them on ebay all the time, there still seems to be a good market for them.
