Crafted with the timeless appeal of solid brass, this vintage door knob back plate is a genuine antique from the 1900s. Its oval escutcheon rosette design adds a touch of classic elegance to any doorway, reflecting the distinguished style of the era. Ideal for those who appreciate the historic value of their home décor, this unbranded back plate is a testament to the craftsmanship of the past. The antique brass finish lends a warm, vintage patina that will complement the salvage features of your space, creating a unique and authentic ambiance. Old with patina. Non-magnetic. Approximately 4.5" x 2.5" with 1" diameter hole. I believe it is brass but could be copper. Please see photos as part of description.
