antique Eastlake door knob, heavy solid brass or bronze door hardware w/ original patina

Authentic Eastlake vintage antique solid bronze door knob... this is quite heavy, cast bronze or brass, with original patina (and a few smears of old paint). A nice architectural art element in the Eastlake, Art Nouveau, or Aesthetic Movement traditions.

This doorknob measures about 2 1/4" across and has an about 1/4" square, non threaded, spindle socket.
