A fascinating antique medical artifact: a complete, boxed galvanic electrical apparatus set manufactured by The Cavendish Electrical Co. Ltd., London. Housed in a beautifully preserved, dark wood dovetailed case with a leather handle and secure front latch. This set is a textbook example of early 20th-century electro-medical quackery or therapeutic device design.
The Box & Exterior: The case itself is a work of traditional craftsmanship, featuring detailed box-joint corners on all visible edges. It is split-level with a hinged top and a lower front storage flap. The top lid features two recessed, nickel-plated contact buttons for easy external connection.
The Interior & Components: Upon opening the lid, a complex control panel of brass, ebonite, and metal components is revealed. As seen in the detailed views, the panel includes:
-
Induction Coil: A detailed, double-wound coil assembly with a brass vibrator/interrupter.
-
Voltage Dial: A rotary dial selector for power control.
-
Brass Selector Switches: Multiple knife-style levers marked “OFF”, “ON”, “P”, and “S” (Primary and Secondary coil selectors).
-
Connectivity: Four prominent brass binding posts/terminals marked “+” and “-“.
-
Accessories: A deep front storage compartment holds various original accessories, including multiple nickel-plated medical electrodes, wooden handles, and a wire probe. A separate, hinged lower compartment holds a complete coil of original, fabric-insulated connectivity wires (green and red).
Manufacturer Markings: The manufacturer’s label is fixed inside the upper case, and is perfectly clear, reading: “THE CAVENDISH ELECTRICAL CO. LTD. X-RAY & ELECTRO-MEDICAL APPARATUS, 105-107, GT. PORTLAND ST., LONDON, W.“
Condition: The entire set is in exceptional, original condition. The wooden case is structurally sound and retain a beautiful, deep patina with minimal scuffing. All metal components appear intact, original, and free from significant corrosion, just demonstrating a soft, authentic oxidation and patina typical for antique electro-medical equipment. All accessories, including the fabric wires and electrode handles, are present, making this a highly complete and museum-quality collector’s piece.
This is a museum-quality example of early medical tech, complete with rare original accessories and in beautiful aesthetic condition.
