Antique Glass Knob Door Lock Set with Brass Rosettes

This item is an antique door lock set featuring faceted clear glass doorknobs mounted on brass hardware. The doorknobs themselves are multi-faceted, reflecting light and creating a decorative effect typical of early 20th-century residential hardware. Each knob appears to be approximately 2 to 2.5 inches in diameter. The hardware components include a brass faceplate for the mortise lock mechanism and two rectangular brass rosettes (or escutcheon plates) designed to cover the boreholes on either side of the door. The brass components exhibit significant patina, indicating age and exposure to elements, with areas of darkening and possibly some verdigris, though the image quality makes precise identification difficult. There is also a visible metal tongue, part of the latch or bolt mechanism, protruding from the mortise lock body. The overall construction suggests a robust design typical of period hardware, likely dating from the early 1900s to the 1930s. There are no clear manufacturer's marks visible in the provided images. The condition points to wear consistent with long-term use, but no major cracks or chips are apparent in the glass knobs. The tarnished brass suggests it has not been recently polished, retaining its original aged appearance, which can be desirable for antique collectors. This set embodies a classic, utilitarian-chic style that was prevalent in homes of its era, combining functionality with a touch of elegance.
