Regarding two of the above mentioned pieces I once saw the Trophy baseball radio in the original box at the Pier Antiques Show in New York City about 15-20 years ago. The radio was mint, the box was nice, yet it is a somewhat generic brown carton (has the trophy logo on it). It was priced for $2,000 which was a ton of money at the time but it sold during the set-up (I was shocked). Back then the radio alone brought about $600 in that close to mint shape which is pretty much what it brings now. Remember to always look for the trophy metal logo on top of the speaker. Its usually missing.
The best variation I ever had of that radio was a version presented to the Homestead Grays for winning the 1946 (?) Negro National League Championship. I have seen two of them. The first one was found in Maine (my mom and dad found it) about 25 years ago for about $200. It as presented to Raymond Brown, although it did not have his name on it. I do know it was his because it came with a sterling silver plaque presented to him for pitching 13 or 14 scoreless innings against the New York Yankees in an exhibition game. I ended up getting them both back years later when the guy I sold it to sold me his Negro League collection.
By the way, there was a cherry of a Darktown Battery bank in my last monthly internet auction. Sold for $4,863 which I think is a great deal. Have you ever seen a nicer one?
