Hi i can't seem to find which pins I'm suppose to connect to on this old Noble Pot i found on some casette tape recorder from like the 80's. It was connected with 3 wires but has 4 legs, one wasn't used(the 2 next to 3 on pic).

Multimeter Measurements: 50k pot / 200k on MM : with pot in middle
1+3 = 43.8
1+2 = 08.3
2+3 = 37.2
2+2 = 0.00
