This authentic antique interval timer was manufactured by the Victor X-Ray Corporation in Chicago, IL, circa the 1920s. A pioneer in early medical imaging equipment, Victor produced these mechanical timers for laboratory and clinical use to accurately track intervals up to two hours. It features a heavy metal case, a classic bell alarm on top, and a detailed face showing both "Minute Circle" and "Hour Circle" graduations. The lever at the side starts the mechanical movement. This piece is a remarkable example of early 20th-century industrial medical history, perfect for collectors of medical antiques or as a unique conversation piece. Sold in unrestored, as-found condition.
