looks as though its a rotary encoder but with end stops

this will be fun.
Others have got to that stage so it is presumably exposable without hickups
Some screws hiding under flopped over electros and one under the daughter
board that has to be released to get to that one. The LCD ribbon connector
needs the closure pulling away 3mm from the pcb to release the ribbon.
It is a stereo resistive volume control with 4 concentric tracks.
Inner and next are conductive and the 2 outer 10K resistive - of the 2
wipers , one connects tracks 1 and 4 and the other 2 and 3.
Desoldered the 2 isolated mounting points to avoid desoldering the main 7
pins as they are sleeve/thru soldered ,
bending over and prizing/parting the 2 parts of the pot.
One of the 7 pins seems to be isolated from the tracks and i cannot see what
it would be connected to as 6 pins only are required.
It looks as though the dropping just slightly parted the metal clasp part,
holding the wiper and spindle, from the tracks part.
