Not tested for working. Wooden box with three button switches for the famous guessing game of which one works the buzzer. The box is clear on the bottom so audience may see the workings. What the audience doesn't see is a wood box that hooks on your belt with a button switch to activate to create the buzzing sound.

The box with switch is hallmarked with Stillwell stamped in the wood. No guarantees as to working but you might just be surprised. This is a very scarce item. In as is condition.
