I think a pic of the underside is near essential to avoid "issues" here. IS it a stereo pot? Looks like a mono to me, but could be just a compact stereo one? If stereo someone may have drilled the pcb, a consideration for future value. Also what is the distance from pcb to spindle, and what is the diameter of the spindle/screw thread passing through the Fascia, and is the spindle 6mm, 6.3mm, 1/4 inch, slotted, etc. Also what is wrong with the one currently fitted?
