motor is a model 40555. which is a 1975. every picture I see the motor is a different color. my motor is blue and the last picture I saw the motor was a green color. just looked at a 1973 on Ebay and it is the same color as mine. can anyone supply a link to a picture, or tell me what is the correct color. Kiya is crazy name for the forum but the only one I could come up wit when I registered. my sieberian was laying beside, whose name is Kiya. hence the name.
