This is the main unit of a Metal Detector, Whites 'Gold Master', Model GMS63. It has some paint scratches, and the Volume control does not turn! I didn't try to force it, may need some attention. The meter is very sensitive, swings when I move my finger on the plastic cover! Must be static electricity, it's very dry here in New Mexico. Looks like it would be a good parts unit, or who knows, it may work with the other part if you could find it! 'But-It-Now', plus actual FedEx Ground shipping to your address in the continental USA only, (No P.O. Boxes). No international shipping. PAYPAL ONLY. Thanks for looking!

I found the white volume control knob! I will add a picture of it soon. The unit is already packed, so I will sneak it in inside an envelope. Thanks!
