I have this unit, sold to me as NOS and looks like it really is. Just hooked it up to an ohmmeter and it is off at off and has varying resistance when twisted clockwise. I also have two other units, but one has different connection points than this one. Not sure what is on a Pantera but you can compare my photos to what you have. Will sell/ship to you for $50, money back if it won't work right for you.
