notes: label: Description (Brief)
content: A wooden base on which is mounted two brass binding posts, a brass post with a rotating crystal turret, and a brass post with two adjusting screws and a plunger maintaining tension on a cat’s whisker. The turret contains 10 crystal fragments that can be engaged by the cat’s whisker. No extant maker’s marks. The wooden base is the same color and finish as the display cabinet this detector is mounted in, and so is almost certainly not original to the object.
