Weird.  That would make it 5.12 Kohms with a tolerance of +/- 5% perhaps?
 
Anyone know for sure?

Close! It's an Allen Bradley hot molded resistor with a value of 5.1k 1/4watt 5% tolerance. These are really deciphered with the 4 band charts. The yellow band is special and indicates the highest level of military specifications. They are no longer manufactured, but were famous as they had the highest reliability of any electronic component. They are still highly valued for spacecraft and military applications and frequently sell for very high prices ($1+ each even in bulk).  
 
Now we build the circuit with a metal film 5.11k 1/4watt 1% tolerance.

Mica, Thanks so much! Not long before this project of mine is finished, with your added valuable information.
Kind Regards
Slawie

Mica,
I found, on the internet, the resistors in Brooklyn of all places.
5.1 K ohm 1/4 watt - Allen Bradley 100 pieces for $31.
The place is Leeds Radio/Leeds Electronics 68 North 7th Street, Brooklyn NY 11211
link to their wabsite is;

incase you are interested.

So if any other club members need that particular resistor, Slawie apparently has 99 extra.

Well,
My bass is finally back together and sounding as great as she ever has.
Thanks to all you guys for your assistance!
Now I'm off to find a band.
Slawie

Congrats!
