What you have are two basic homeowner radios, one from the 1930’s (the 141) and one from the late fourties or early fifties (the 320). Unfortunately the 141, although a very attractive set, is in need of some cosmetic work, with the grill cloth badly torn, among other things. It would probably have the most value of the two, but I wouldn’t make plans to go and buy a new car (just kidding). I doubt that either of these would fetch $100. It’s too bad, as I imagine that your grandparents might have bought these new? and obviously enjoyed them as they kept them long after they were not really usable any longer.
Service data is available for both of these should you decide to go about getting them restored as keepsakes.
