Rittenhouse Sentinel Model 365
Described in a 1950s Rittenhouse Catalog:
The Sentinel – High style and performance at a moderate price. This model is available either with 3 tubes or with 2 tubes. Both models sound two rich, resonant tones fro the front door and a single-note for the rear door. Ivory plastic housing with gold finished decorative motif. Tube finish, brushed brass. Has Rittenhouse “Floating Percussion” mechanism which insures quiet, long-life operation.
In order to achieve the moderate price point, the Sentinel has brass-plated steel resonators instead of the solid brass used on the Beverly. Notably, the Sentinel has a decorative center resonator tube.
A later iteration of this chime with two resonators features a stylized eagle in place of the lyre and are known as the Rittenhouse Newport model 314.
