I have 1 Door Knob brass ornate Vintage Salvage item. It dates from between
the late 1800's to early 1900's or so. The knob is very ornate brass a bit
heavy. It has a square center rod which would fit in the back (this is just the
knob, no rod) . It measures about 2 3/4" across the top x about 2 1/2" in d. I
would consider it in good condition, there is some tarnish.
