Dale, that's interesting. I have a BF Goodrich Mantola R419 portable. (one of the 1st gen models of portables that came out in 1938). Belonged to a great-uncle. Had 2 45V bricks and 1 1.5V Brick and the requisite 3 plugs.
Just looked at the RadioMuseum pix. First off, that battery is GARGANTUAN, much bigger than the batteries in my portable and about 1.5 times the size of the battery area of my portable.. However that is to be expected as the farm sets were stationary. However, it seems that there are plugs at the top and bottom. The first pic shows a guy holding the battery. The second pic shows the 4 pin jack on the top right (or left depending on point of view and orientation) and the 3 jacks you mention at the bottom. As if it was to be a universal battery for sets using those voltages (and there were many).
