This stamped brass doorknob set was made by the Reading Hardware Company of Reading, PA. The pattern is called “Eulalia.” The knobs are a drum shaped, flat across the top with a shallow round depth.
We have not cleaned the set; they maintain an aged brass patina. The knobs measure 2 1/4 inches across and only one inch in depth. The set consists of two matching knobs, a spindle and two set screws.
