Rare Early 1800’s White Porcelain Doorknob Set

This toadstool shaped doorknob design was one of the first used for glass and porcelain doorknobs.  The metal has been polished and is now shiny silver again. I suspect the metal is pewter since the rosettes are quite soft. The porcelain has some discoloration on sides/back of one knob (sort of a cloudy gray) but the other knob has only one tiny scratch and there are a couple of nicks/dents on one rosette. Not bad after all these years of use!

Now for the technical stuff!  One doorknob has the spindle pinned and the other doorknob is attached by a pin through the entire ferrule.  The original pin was missing and I’ve included a steel replacement. This spindle is currently sized for a door 1-1/2” thick.  For a thinner door you would need to cut the spindle (before drilling a hole for the pin) and if your door is thicker you will need to replace the entire spindle. To replace the spindle you would need a 1/4” square rod that you would drill holes in. Tap the pin out of the doorknob and re-use the pin in the new spindle.

Doorknobs are 2-3/8” in diameter
Doorknobs sit 2-1/4” tall
Rosettes are 1-7/8” diameter
