This is a very old knob, probably pre-1900. We are not sure what piece of furniture this type of knob was on, but it has the smooth shank with a “finger” screwed to the shank. The finger functions as a nut. It can be adjusted on the shank wherever needed and then tightened down with a set screw. Because of its elongated shape, some hardware-men suggest that the knob could have be used like a latch, meaning the finger catches behind a center column or another door.
The stamped brass knob consists of three pieces, another indication of its age. The top was crimped onto the base, and then a stem with the shaft attached to that. The remarkable feature of this old one is that it has no dents in the top which is common for very old stamped brass knobs.
The knob measures 1 1/4 inches across the top. It projects one inch from the surface. The stem spreads out to 3/4 inch across. The shaft is 1 1/2 inches long. The cast iron finger is 1 1/2 inches long and 3/8 inch wide. The set screw is loose and usable.
This antique is a fine specimen. We are proud to be able to offer it to you.
