Rittenhouse Tulip Model 285
This Rittenhouse Tulip chime is painted with a stenciled floral design. The Tulip had the lowest price point of any resonator chime at the time. It was also one of the last metal covers in the Rittenhouse line.
A 1949 Rittenhouse price list describes the chime:
A gay new chime… Authentic, colorful Pennsylvania Dutch design… sounds two melodious notes for the front door, a single-note for the rear door. Easily installed on regular doorbell wiring and transformer. Available with ivory, red, or green tubes; face of chime is ivory embellished with yellow, green and red design.
Red resonators, as shown in this example seem to have been most common.
