The product is an antique early 1900s door lock featuring white porcelain doorknobs. The door lock is made of cast iron and porcelain, giving it a sturdy and elegant appearance. The rectangular shape and white color of the porcelain doorknobs add a classic and timeless look to the piece. This antique original door lock would be a unique and charming addition to any home, particularly for those with an appreciation for vintage architectural elements. Knobs turn latch but don't have a key to lock.  You can remove this doorknob from the section of the old door & use it as you choose as a fixture.
