An intriguing late Victorian portable faradic electrotherapy apparatus by K. Schall of London, dating approximately to 1890–1900.

Housed in an attractive oak carrying case with dovetailed corners, a metal handle and brass catches, this instrument offers a fascinating glimpse into the early history of electrical medicine. The circular maker’s label on the lid identifies K. Schall, Wigmore Street, London.

Opening the case reveals a brass instrument panel with electrical terminals, substantial lever switches and an exposed electromagnetic interrupter. The apparatus retains its distinctive wooden-handled sliding core, marked with a scale from 0 to 10. Moving this core within the induction coil allowed the practitioner to vary the electrical output, with the graduations providing a reference for repeating settings.

Machines of this type generated electrical pulses applied through electrodes for muscle and nerve stimulation. Included are the cylindrical metal hand-grip electrode, wooden-handled electrode fitting and fabric-covered connecting leads shown in the photographs. A removable drawer lined in green felt provides storage for the accessories.

A compelling addition to a collection of antique medical equipment, scientific instruments or Victorian technology, with an appealing combination of oak, brass and visible mechanical detail.

Condition: Age-related scratches, marks and small chips to the wooden case, with tarnish and surface oxidation to the metal components. The connecting leads show wear and deterioration. The graduated core retains its numbered scale, with wear to its covering. Please examine the photographs carefully for condition and the included accessories.
