You are meaning a fair price your co-worker should pay you for taking it off their hands? The word "work" is just not definitive enough. What are you going to do with it? One concern is it has a selenium rectifier unless replaced. There's not much to these sets; it is 1957 too. Really, your co-worker should just give it to you for nothing if you aren't in the re-selling and plan on fixing and keeping. Or the next time someone retires and you all eat at the Chinese Lunch Buffet, pay for your co-worker's meal. Does not include drink!
:A co-worker of mine would like to sell me the above item. We do not know what a fair price for it would be. It does work, but does not have the original legs. Could anybody help me with a price?
