[Hallicrafters] Resistor coding

[Gerry Steffens]

There are two possibilities of which I am aware.  First is a temperature
coefficient the second is (if I remember right) British standards can have a
quality or grade of the resistor in the fifth band, if present.

I've been sorting resistors into individual-value trays and have run 
across a few resistors with 5 color bands.  For example one in my hand 
now has:
Red-Red-Black-Gold-Yellow which is a 22.0 ohm 5% but I'm wondering what 
the fifth band represents.  The Allied book doesn't address 5 color 
bands, neither does Radiotron Designer's Handbook.  Thanks.
