• Notes
• Hi-Mound Compound Key MHK-831.
  Scarce and unusual dual key made of brass. The knob on the right side of the base physically adjusts the separation of the two identical paddles. The little round shaft protruding forward on the hand key is actually a spring loaded plunger that acts as a shorting switch.
