There was often a 4th band for tolerance, none = 20%, silver = 10% and
gold = 5%. Wattage determined by size, This for all composition resistors.
Wirewound precision resistors usually had the ohm and tolerance printed on
them. Hi wattage wirewoounds usually on a ceramic core also had ohms printed
I used a lot of diff. kinds in my work from building HI-FI AMPS to ultra
precision weighing system calibrators for the Atlas missle launchers.

Never heard of Milli Amp nor Micro Farad but only recall the resistor saga
from hearing it once or twice.
