That's a new one on me too, in the same pot.

I experienced that in combination on two pots when I was restoring the HMV 904. On one the carbon track had visibly broken about 10% from one terminal hence no connection end to end. On the other one bad handling meant the wiper had broken from the shaft, which was rotating freely, and the wiper wasn't connecting to the carbon track.

To have both those faults in the same pot is probably fairly unique

Please say what you discover is the cause ... Bad connections on all connections would be the mundane answer

As far as what I did to fix things, I superglued the wiper back onto the shaft (the original mounting had been shattered), and used silver paint to reconnect the carbon track.
