You are bidding on a Large Antique Ornate Door Knob, Back Plate & Lock Set for Parts or Restore. 10.75" long back plates. 4.75" wide on one side and   3 7/8" on other. Key fits and turns but the mechanism must be broken inside. Back plates curve in slightly on end. Door knob does not turn, the dead bolt does pop out. This looks like it will fit a 2" thick door not sure if it will go smaller for a standard sized door.      If you get a chance please visit my store, cj's small treasures, for other great Buy It Now items.  I know nothing of its collectability, so please view the photo and bid accordingly.  If you have any questions please email me before bidding.
