There have been several versions made of the 9-1070 open station toy tractor since 1970. Ihis is a pic of the first Ertl 1070. Google CASE Toy Tractors and you will find several toy dealers on line.If you want to make an exact replica of his tractor, google Dakota Toys and you can order dual wheels and tires, plus 970 decals, and other accessories such as 3pt.
The last 2 pics are of a custom 930 toy which I built a proper front axle, cab, and swinging drawbar with 3pt., and the last pic is of real one that the toy was modeled after. I plan on building a replica plow for the toy this winter.
