[Farmall] F-12 Paint Color

[Johnny and Bobbie Walton]

I am trying to restore a 1936 F-12 and don't know the correct color.  I've seen plenty of pictures, but some are red and some are gray.  Does anyone know where I can find the correct color and what the paint color codes are?  Also, this tractor has a Fairbanks-Morris mag on it and I'm wondering if this was the original.  I'm new at this, so any help will be appreciated.  Thanks, Johnny
