Morzh,

I don't know if this helps, but I found an old article in Philco News dated September 1931 page 12 that states: "Starting with the Model 46 and continuing in all future models, standard R.M.A. colors are being used to indicate the value of various resistors in Philco Receivers." It continues to list part numbers , color codes and resistor values. I cant up load the page right now. It clearly states that Red body, Yellow tip and Yellow dot is 240k, 1 watt P/N 3768. It also has the same color code for a 1/2 watt P/N 4410.
