Shown here, 75 years ago, is the assembly line of Templetone Radio Mfg. Corporation. The picture appeared on the cover of Radio News, August 1947, which noted that postwar radio sales were at an all-time high, and that this assembly line was typical of the activity of radio plants throughout the country.

The factory was located at 100 Garfield Avenue, New London, CT. The building still stands, and is shown below. It was built in 1920 and originally known as the Edward Bloom Silk Mill.
The building, judging from the Google street view below, appears vacant, but is apparently in the process of being converted to housing.
