Very nice looking, vintage 1951 Chrysler AM push radio, Mopar model number 815. We have had several of this type Mopar radio of the era but never found a power supply/speaker setup to properly test these. This has the 5 pin plug that most of the Mopar radios of this period had. We put power to this one and one or more of the tubes lit up, so it has juice through the switch. Also switches off properly. The rotating dial works easily and is very nice. That's all we know so we're selling cheap, as is and no returns
