This impressive industrial-era Siemens Type OVE3 desk fan, dating from the early to mid-20th century, features a striking four-blade brass impeller enclosed within a minimalist wire guard and mounted on a robust, black-enameled cast-iron base. A quintessential example of German engineering from the "Golden Age" of electric fans, this model is celebrated for its heavy-duty oscillating mechanism and stepped speed control, reflecting the transition from strictly functional machinery to stylish household appliances. Measuring 42.5cm (h) x 32.5cm in diameter, the unit presents in good vintage condition with a characterful aged patina to the brass and minor surface wear to the enamel consistent with its age. It has been tested and remains fully functional, making it a rare and evocative statement piece for any collector of industrial antiques or mid-century decor.
