1957 Vintage Oldsmobile am push button. GM part number 989001, serial number ow 6571. Used on "88" series cars. Golden Rocket 88, Rocket "88", and Super "88". Radio has been storage for 50 plus years, it appears to be complete. On/off switch turns freely, tuner knob missing retainer scew,  radio station needle does not move. Have to believe it is due to setting all those years. Radio needs to be thoroughly cleaned and inspected. Ask questions. Will combine shipping when possible.20106 15 6s
