Rittenhouse Beverly Master Model 526
A 1955 Rittenhouse sales brochure described the then new chime:
Beverly: America’s most popular melody door chime. Completely restyled for use in contemporary homes. Cover is lovely walnut or limed oak finish with gleaming brushed brass tubes. Sounds rich harmonious four-note melody for the front entrance single note for the rear. Embodies famous Rittenhouse “lifetime floating striker” as well as adjustable volume control and shut off
This iteration of the Beverly lasted until the mid 1960s when it was replaced in the catalog by it’s contemporary, the Prelude and then reintroduced by the more conventionally sequenced motorized Beverly Chimes.
