Their radios were known as Air Chief. The two smaller radios in the middle are models 4-A-78 (Brown) and 4-A-79 (White) and I think are kind of rare. It looks like a battery portable to the left of them, maybe a 4-C-16. Here are some websites to help you id them:

Stewart-Warner, Sparton, and Detrola made a lot of their radios over the years. I think Sparton also made tv's for them too.
