Dug this in an old farm dump. The wire was coiled around the porcelain and protected the porcelain body but the glass top took a hit. Porcelain reads Sterling Electric CO. / PAT. MAY 20 & AUG. 5-90.
Left the key and some other parts behind which I need to go retrieve. With any luck the key will have Sterling stamped into the side.
------Turns out this is an old battery and is common-----
No Sterling insulators dug...2 Brookfield kegs & 1 AMTEL toll
