Collection of four antique vintage white ironstone porcelain doorknobs. These are the original vintage doorknobs, not reproduction hardware. These door knobs measure 2 3/16" and 2 1/4" across and almost 2" high. One of these door knobs has a brass mounting shank and two have the remains of the original black paint on the iron shanks. The three iron connecting shanks measure about 0.3" square.
These old doorknobs are in very nice vintage condition.
