I've had one of these in the basement for quite some time. I got it from my folks, who picked it up at a garage sale (?) someplace. I had wondered exactly how old it is, but until now it'd never occurred to me to look up the model # on Google. Duh.
According to this, it's from 1937 and was worth $30 brand new. I don't know how much this one would be worth--it's not exactly in tiptop shape, although it does work.
I have another radio upstairs, although that one is different (it's much larger and even has a pullout turntable! ZOMG). I got that from a girl two blocks down the street who was moving to Barcelona and selling everything. I'll have to look that one up too.
