Lot of 6 pairs of door knobs and escutcheons manufactured by Norwalk Hardware.  The pattern is called LOUIS XIII or Barocco in their catalogs and was manufactured between 1899 and 1909.  Oval escutcheon plates measure 2 1/8" x 7".  Door knobs have a diameter of approximately 2 1/4".  The hardware is cast brass or bronze.  Knobs show wear to finish from years of use.  Mortise lock bodies are cast iron with a cast brass or bronze face.  Lock bodies are marked Norwalk.  All were salvaged from the same house prior to demolition.  One set does not have a mortise lock.  One lock has a working skeleton key.  All set screws are present.  Several locks have strike plates, most match.  You will need screws for the mortise locks and escutcheon plates.  Great patina.  I will leave final cleaning up to the buyer.  Each complete set weighs 2.34 pounds.  Sets will be partially disassembled for packing and shipping.  Please ask any questions prior to bidding or buying.  Additional pictures and measurements available upon request.  All sales final.  No returns accepted.  Please check my other listing for similar items.
