The was a film put out by the Oliver Tractor Corporation in the late early 1970's to dealers. promote the new 1800, 1900 tractors (in both row crop and weatland), and a wide variety of the implements. This also contains footage and promotional information on the 50, 550, 660, 770, and 880 model Oliver's I do not claim any copy-write over this video, and to my knowledge it should be public domain. It was converted from an old VHS of my father's. I believe this was also for sale at one time in the Floyd county museum in Charles City IA.
