Westinghouse 10 Transistor Radio - $30 (Leon, Iowa)

About as close as you can get to a brand new 45-year old transistor radio.
Maybe it's older; I don't know.
It's AM only, so that's a clue.
Complete with original box, owner's manual, earphone, and I'll leave the batteries in, if you'd like.
I've listened to it some, but there's a lot of life left in them.
Sound is good, a bit better than some of the earlier shirt pocket radios.
It doesn't work well inside my apartment, but I sat outside with it several times and it gets a fair number of stations.
Might be even more for you, if you live in a metropolitan area.
I can bring it with me next time I'm going to the city and we can meet at some convenient location for the sale.
