I have been an ebay user since the early days, mostly as a buyer and not a seller. However I would be willing to start an auction for any of these radios that I would be willing to sell.
Make me an offer and if we agree I will do a private "buy it now" sale.
Alternately I am always willing to trade for sets that better fit into my collection (say 20s to mid 30s stuff, especially Stewart Warners).
So far here is what I would be willing to part with:
General Electric 429, red plastic radio complete with civil defense markers on the dail.
Here we have a Zenith R-511V which is a very bright red plastic set with civil defense markers on the dail and a moving daillamp that shines threw the plastic case.
This Zenith B-508R I would be willing to part with, works fine but has some plastic discoloration on the top.
Here is a Zenith H-715 that I would also be willing to part with, cabinet in near mint condition, works great- gets AM and FM.
With more to come as I get around to take pics of my stuff. I have about 90-100 radios and many are still not featured on this site or pictured.
Make me an offer for sale or trade for any of these that catch your fancy. Generally speaking the rest of the collection is not for sale but everyone has their price... with a few exceptions. Note my 20s sets are absolutely not for sale, nor are my stewart warners but most everything else is fair game if I get "an offer I can't refuse."
