[R-390] Receiver vs 51J-4etc SLUG CORE SIZE, COLOR CODING ETC.

[ELDIM]

Hello Group,
Is there a  size difference (Length & Diameter) ofthe powdered iron SLUG
COREs for the 51J4, R-389, R-390, etc. Radio Receivers?  Can the color coded
dots be deciphered to  a  value associated with each core?  Is there a
central archive for each type receiver explaining the different core
materials and which color coded slugs go to which Transformers?
I'm definitely interested in knowing.
