Sickle mower paint colors.

[Barrier 27]

I got an older handle lift sickle mower recently. It’s the 210 model. It came to me as a Simplicity unit. I however want to match paint it to my 64 Allis B10. Can some one tell me which parts if any should not be yellow? I would like as best I can to paint it the correct Allis colors.

The idler pulleys and the drive pulley were silver. The support chain was  probably cad plated. I believe the knives were unpainted. The rest of the mower including the swathboard was painted yellow.

I have always used old cat yellow.
