Geoff,
Yes, this probably was a substitute for a 6K and someone (probably factory) made a fixed-adjustable out of a wirewound. They used a wire-wound and scratched off the ceramic coating, so a dimple in the band could touch the resistance wire.
The band was probably was bumped at some time and the contact point on the inside of the band no longer touches the resistance wire. Check to see if this has happened, or it might simply be that the connection just corroded over time.
