This is a listing for a "Only Gold Flakes" design lucite doorknob. This door knob has a small hole drilled in the center of one of the knobs. You may also see my other 2 listings where I have the same doorknobs listed separately: one listing is a set of three that are in excellent condition and the other listing has a minor imperfection in the smooth surface.
These were designed by Sarasota designer/contractor Ruth Richmond, this set consists of two knobs, face plate and a latch. These date to the 1960s.
Knobs measure approximately 2" in diameter.
All doorknobs come with door latch and latch assembly.
**The drilled hole can be seen in the pictures.
