Really interesting.

I have this one old radioamateur book from 1957 that mentions old colorcode system used in GB and US manufacturers ( with mention that some of them still did use it ). I assume it is one RETMA or the standard system derived from there.

The description of system is as follows (my translation):
"The resistor body color gives the first number, another end of the body have different color and gives the second number and amount of zeros is indicated by the colored dot in the middle of the body. The color and number relation is the same as "Vitrohm uses"." (the same as is used today, Edit. Color indicates number of zeros not multiplier. ..oh, never thought or paid attention before, multiplier of todays system gives same amount of zeros ofcourse since 10^x notation, silly me. ).

For the actual subject I have no further information.
