Jack, Hydro Harry already addressed the starter generators, I agree they should be yellow unless they are a replacement. From about a decade and a half of observing brochures, photos of tractors and attachments and actual tractors and attachments here's my best guess on colors. I believe the very early, say the first few months of production at best had white mower deck spindle guards and mule drive cover plates. After that they would have been yellow. The 26 lb wheel weights were originally made as front wheel weights for the Farmall Cub and would have been painted red. After the Cub Cadet was introduced and the weights were sold for use on them I believe they became available new painted yellow. I believe they did not show up painted white until the introduction of the 1x6/7 series. I base this on photos in a few different brochures. All the brochures prior to the 1x6/7 series depict the wheel weights as yellow and in the 1x6/7 series brochures and after they are depicted as white. I believe all the seats on Originals were white. I have never seen one painted any other color. Not saying they have not been painted another color, just that I have not seen one. Initially the voltage regulator was mounted on the front of the battery box. Those that are mounted elsewhere I believe were moved there by the owners. However, I could be wrong about this. Perhaps Craig C. or Paul Bell, two people whom I highly respect for their knowledge about the IH Original and all things Cub Cadet. I have seen them mounted on the right hand side of the pedestal as well. Not sure about the 13 tooth gear, though there have been other ratio gears available for the Cub transmission over the years. You will likely see both white and yellow headlights on them as well. The headlights were used on other IH products over the years, most notably a few different combines and they were white when used on them. Being an option, the IH Dealer might have combine lights in stock that could have been sold for use on an Original. I believe yellow to be correct, however, white could pass as being original too, see my above statement regarding their other applications on IH products. <FONT SIZE="-2">IMO, FWIW, YMMV, My $0.02, Yada, Yada, Yada...</FONT>
