This knob was popular around the 1960s. It is light weight and has the filigree pattern. The center flower has a bit of white paint. This pattern accentuated a French Provincial white-painted handle of the era. The Ajax Hardware Company of City of Industry, California manufactured the knob. The company is no longer in business.
The brass-toned knob measures 1 1/2 inches across and projects from the surface 3/4 inch. It comes with its original screw.
