My dad was just over visiting and I showed it to
him. He says that he
has a similar one that was made in WW-II. He doesn't know what he's saving
his for either. He just says that it looked neat. I guess that I came by
being a pack rat honestly :-/
Most of these batteries were made in World War 2, many by a company called
Willard. They pretty much fell out of fashion roight after the war in new
designs, but probably were still produced for all of the existing radios
(mainly) that used them.
Most are worthless, but some are slightly valuable.
