Thanks Chris I have been looking through  my magazines and literature and found a letter to the editor in The Oliver Collector News March 1994 about a model 7 and a later model 7-A plow that Oliver made for the Fordson. The model 7 had a crank on the rear but the 7-A had the crank on the front like my plow in the picture, they also said the plow was red but no mention of the wheels. My wheels may have some specks of red unsure, but the lift clutch appears to have been green but specks of red on plow frame. I am thinking of painting the wheels green but would like it correct.  Thanks
