Odd Metal Film Resistor

[Jw]

I have here a strange metal film resistor - red red red gold white.
According to all the online references I've found, that combination does
not exist. Now, I know it's a 2.2k resistor (I purchased it) and I'm
assuming the gold is the tolerance, so can anyone tell me what the white
band indicates?

Thanks
Jw

Maybe a fusible resistor, the white band gives the power rating.

Could just indicate the RH end of the resistor, especially if it's a
different width than the other bands and over the end cap.

Thats what my ARRL handbook says, but if I extrapolate from their
numbers (which only go to yellow) it would indicate a 1 PPB (that's
0.001 PPM) change per 1000 hours of service. It either means something
else in this case, or the coding doesn't extrapolate.

_Reference Data for (Radio) Engineers_ says that white is the indicator
for a weldable terminal.
