Dad as kid

This is my Dad on my Grandfather's first tractor in 1942. It is most likely a model 9N which is what Ford made from 1939 through 1942. I am guessing that it was not new. If it was new in '42, then it could be a either a 9N or a 2N which began production in 1942. Ford renamed the 9N to 2N because of some war-time production rules, but it was essentially the same tractor.
