History:
Sentinel was in the 20's the trade name of United Air Cleaner Corp.;
A merger end 20's with Erla and other companies failed and went into receivership. Erla reorganised as a private company in 1931, and apparently bought Sentinel between 1931 and 1934, where it continued to manufacture as Sentinel Radio Corporation.
Sentinel produced radios for an unknown number of private labels (twenty to thirty), some for export. The company name ERLA was still retained until 1945.
e.g. Musicaire was made for Coast to Coast Stores.
In March 1956 Sentinel's assets were sold to Magnavox.
