Thanks, tmad40blue, I've read and re-read your thread to familiarize myself with the procedure. Now if I could just remove the knob. I may have to drill out the tap screw as it will not budge.
Great rare find! If the pots aren't completely corroded out you can use my guide to clean and restore them - the link is down there in my signature.
Keep us updated; I've always wanted to own a pair of these, if only for comparison's sake.![]()
