This solid, heavy door knob is probably cast bronze. Being a Victorian knob from 1895, it has the color and feel of bronze. During this era, the hardware houses often preferred bronze casting over brass. The bronze knobs are darker and deeper in hue.
This knob was made by the Reading Hardware Company in Reading, Penn. and this pattern appeared in their 1895 catalog. It is quite unusual in that it has a concave (or sunken) top and a very wide belt. The pattern continues on the backside of the knob. The knob measures 2 1/4 inches diameter. The belt is 1/2 inch wide. It is a 5-ounce knob.
Because of its beauty, this knob really makes a statement.
