This Imperial is actually a renamed Case model 601 which was
manufactured by the Case Electric Corporation of Marion Indiana.
The Case 601 had three bands and used a mixture of large pin and octal
glass tubes. The later version of the 601, the 610, had four bands
and used all octal metal tubes. This radio was also sold under
the brand names of Silvertone (Sears) and Radio Vogue. The most
interesting feature of this radio is the "Jumbo" dial. It is a large
multi colored, side lit glass dial that seems to be oversized for such a
medium sized cabinet.
Case Electric Corp. was originally known as the Indiana
Manufacturing & Electric Corp., known for the "Indiana Hyperdyne"
and "Case" brand of radios manufactured from 1923 to 1928. It was
in 1928 that the Indiana Manufacturing & Electric Mfg. Corp. changed
their name to Case. From 1929 to 1934 Case did not make any radios,
almost as if the company went dormant. Then in 1935 production
started up for the Case line of radios for the 1936 season.
Unfortunately Case failed to submit yearly corporation reports, which is
required, to the state of Indiana during the years of 1929 to
1934. Soon after Case went back into production, the state of
Indiana held hearings on the future status of the company and on April
2, 1936 the state of Indiana officially dissolved the company.
I bought this radio from a prominent antique radio collector/dealer, from Minnesota, in 1990.
