From L to R Top row: Gladestone-LeLande Primary Battery in Cobalt Blue glaze, Edison BSCO No.3 7 1/4" round, Edison BSCO No.8 6" round. Has a side slot hold down. I think these were used for Radio Batteries, Bottom row: A.A.R. Signal Cell National Carbon Co. NY. Has three recessed holes in lid I'm assuming for stacking or some kind of clamping device. A.A.R. National Carbon Co. NY. Open typr with an oil hole. Unlike the other one, this has the additional embossing of Contains Caustic probably for safety reasons. The two on the left end were in the previous picture description.
