That is not a 1930 radio, Philco did not build an auto radio until 1931 Check out "TRANSITONE" I have a 1930 Transitone it was built by AUTOMOBLIE RADIO CORP, I also have a TRANSITONE 3 that was built by PHILCO in 1931 , Does your radio use "B" batterys? Check out your power supply, if it does not use the "B" batteries it is 1932 or newer , have you a model number? This web sight has a list of 1930's Philco auto radios, 'If no model number send us the number on the tubes used on this radio if you find a vibrator in the radio it is from late 1932 an newer, motor generator it could be as old as early 1932 ,Now to add more confusion there where B elimanators available for early auto radios these where built after 1932
