The Weathers is a very interesting innovative turntable. It had a very light platter so that a very small clock motor could turn it, via a soft, almost spongy disc mounted on the motor shaft -- no idler etc -- and because it was so light, rumble was almost nonexistent. The arm was wood for low resonance, and the counterweight was, in fact adjustable and hung from the bottom of the arm. Some of the Weathers used a very unusual capacitative cartridge that was something like FM modulator which needed a demodulator. It evolved into the Euphonics Miniconic, and than into the Win cartridge.
If that is the cartridge, you'd need the demodulator. And I bet that soft rubber wheel is hardened by now.
I don't think its a very good deal, though it is a fascinating bit of audio history. Weathers also invented the sub/sat system, I believe.
Byethebye -- J Gordon Holt did publicity for Paul Weathers for a while.
