Know anything about this Supro guitar?

I'm not sure what the model is. Maybe "Tremolectric" 440? Big single coil pickups Reso-glass top and back. Its got an electronic tremolo which you can control with the little red switch under the neck pickup.It's actually a circuit with a little light bulb in side and the little switch works like a little electric whammy bar so you use your pinky to wiggle the trem. You can change the sound of the trem from soft to hard by changing the size of the light bulb.

Any idea what these sell for?
