This is a single antique wrought bronze transitional era Cairo design door knob manufactured by P & F Corbin (New Britain, CT) in 1905. This beautiful 2-1/4" knob has a cute swirly face design with center flower and gorgeous, uniform patina. This beauty is mated to its original thick wrought bronze door plate with beautiful color and a crazy gorgeous design...one of my favorites! The plate measures 5-1/2" x 1-9/16" and price is for one of this great example of old all-American awesomeness.Default is as a DUMMY KNOB. What is a Dummy Knob? A dummy knob is for pulling, not for turning. A dummy knob is a face mount knob that acts as a way to open/close a door, pull/push or side to side. Ideal applications are on man doors, cabinet doors, barn doors or french doors...any door that has an alternate method of latching, but needs a cool piece of original antique hardware to pull it open and closed. Other applications include use as wall towel hooks, wall coat hooks, curtain tiebacks or just wall art! My antique dummy door knobs are all actual antique, period specific door knobs that have been mated to a door plate or rosette (the round door plates). Mounting to the surface is via screws through the door plate screw holes (which you supply). Making an antique dummy knob is a process at our end, and most of the knobs that I have are not yet assembled (in order to give the client the option of Dummy or Operable). Because they are "made to order", it typically adds 2 to 3 days onto the order process time. If you need them quicker, please sent a note with the order and we will see what we can do to speed the order a bit.OPERABLE KNOBS: As with most (NOT ALL) of my dummy knobs (surface mount pull knobs), these knobs can or may also be purchased as STANDARD OPERABLE KNOB SETS. As dummy knobs, we typically permanently connect the knobs to the plates when they are ordered (although there are a few that are pre-assembled as dummies). The DEFAULT is dummy knobs, so please specify via a note with the order (or an email) if you dont want them to be dummies, but that you will want them to be live, operable turning knobs to be used with a mortise lock. With most PAIRS of operable knobs I will include a knob spindle and knob set screws. Plate mounting screws will be supplied by you as required for your installation application.CUSTOM KNOBS SETS OR COMPONENTS: If you would like a custom set or multiples, or maybe just parts and pieces of what you see, please feel free to drop us a note and let us know your questions are, or what you might need!Thank you!
