Nice choice with the standard trans. Far more reliable than multi-power. A friend of mine down the road used to work at his father Massey dealer until 1994 when they closed. N.H. Flicker and Sons. He helped me get the details exactly right. He told me that the tool boxes were put on at the dealership and that the dealers were buying them from whoever was cheapest. The box I had on mine was labeled from Des Moines, Iowa. But the tractor came from the local area. So if its any help, watch on ebay and you'll find a box that is pretty close to the time period boxes they were putting on the trators in the 70's.
