I found your radio in my abridged riders volume I-V but GMR did not appear in any later. The Abridged volume Radios are from 1930-1935.
I assume that General Motors Radio was a division of the GM today. In the 30's radios where "The Fad" I think just about everyone built them. I even seen a few by B.F. Goodrich.
There should be a schematic on this site in the rider volumes that they have scanned in. I don't know the exact number. (don't have an index)
Good Luck

General Motors Radio Corp. was an axtension of the Dayton (Ohio) Fan company, an early producer of radios. Charles Kettering and RCA, both owning about half of the company, absorbed the Day-Fan radio company, and named it general Motors Radio Corp. RCA's interest was kept quiet, and in about 1931 when the independent Radio manufacturers had RCA in court to break the RCA monopoly of the Superheterodyne patent, RCA deceided to quietly slip out of the GMRC firm.
During the period of 1930-1932, General Motors radios were fine sets. The models 120 through about 160 were handsomely built, nand housed in period cabinets of superb quality. There were superhets before they folded, and the "Little General" was a very popular "midget" set. I am told that Delco Radio was NOT an offshoot of GMRC. It came a few years later. The first radios offered for automotive service in the early thirties were labeled: United Motors Service.
