This is my scan of the original.
Print this to scale.
To assemble, place 2 AA cells side by side, one reversed. Solder
a thin strip of metal from positive to negative. Wrap with kraft
paper, oaktag, or lightweight cardboard., including bottom of battery.
Fill top with beeswax from old caps, hot glue or titebond. Original label
was coated stock, so a light coat of spray lacquer, fixative, or what-have-you,
if desired, to make it shine. Original battery terminals were
thin strips of metal sticking out of wax on the top. Paste onto completed
battery, leaving a bit on top, fold under bottom and tuck in neatly.
Age/distress to taste.
