Impressive how little that battery leaked over all those years It was very likely one of batteries where each 'cell' looked like a block of compressed charcoal, about an inch or two square, with a strip of plastic around the edge. When I was a kid back in the 1960s, we used to pull these apart and throw the cells around like stones. The most common size radio battery then was a 45 v battery, about 7" x 5" x 2" (IIRC) with a small socket in the top of it. https://www.flickr.com/photos/unclegal/31122957375 https://www.flickr.com/photos/unclegal/31122957375
