This is an incredible antique Art Nouveau exterior door hardware set, made by Branford Lock Company, featuring its original chrome over bronze finish. Circa 1893, the chrome plated "step-down" knobs are ornamented with a radial design in an abstract floral motif surrounded by beaded and scalloped bands; the backside of each knob is also ornamented with stylized foliate details. Each beautifully cast plate has an Art Nouveau design with diagonal panels featuring scrolling foliates, radiating lines and beaded detail. This exterior set includes two door plates (one with its original cylinder lock), and the pair of knobs with their connecting spindle (enough hardware for one door.) The door hardware set is in very good antique condition with a beautifully aged patina. The doorknobs measure 2-3/4" wide and project 2-3/4", the plates measure 3" wide and 12-3/4" tall.
