Now don't put my brains in the fire!

Long ago, in some publication on radio, I had read, that, the Philco production environment used a LOT of mercury lamp illumination. Because the light was so rich in UV, normal color codes could not be used. Thus, odd ball colors.

Given that dog bone resistor drift and production line changes did not always get recorded, we, see the resistors as they are, different.

Dog bones like paper caps are way beyond end of life. I abandoned using measured values of dog bones (re-paints). I found that they continue to drift from the current flow and even moderate heat, have gotten noisy too...

YMMV
