antique heavy cast brass door knob, Eastlake vintage door hardware w/ original patina

Authentic early century antique door knob... this is quite heavy, cast brass or bronze, with original patina. A nice architectural art element in the Eastlake, Art Nouveau, or Aesthetic Movement traditions.

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