Vintage rim lock / door lock mechanism with knob
Estimated Value
$25-$100 as-is; potentially higher if identified as a desirable maker or complete working antique lock set
This appears to be an old mechanical door lock or latch assembly, likely a rim-mounted lock or similar surface-mounted locking mechanism. The piece consists of a flat iron body plate with multiple mounting holes, a protruding cylindrical housing, and a large round knob or thumb-turn style handle. The metal shows extensive age-related corrosion and patina, suggesting long-term use and storage. The form is utilitarian rather than decorative, consistent with period architectural hardware used on interior or exterior doors, cabinets, or gates. No clear maker's mark is visible in the image, though faint stamping may be present on the plate.
