This is the first one I have seen. A 5 and 1/2 inch diameter dry-process, porcelain battery jar lid with a cobalt blue glaze. Embossed "GLADSTONE-LALANDE BATTERY" in an arc. Also embossed in three lines: "PAT.AUG 2. 1892./ JUNE 2. 1903./ NOV 3. 1903." Read they were used with a porcelain battery jar for telephone or telegraph communications. There are two small chips on the back side: one on the back of the lid and another near the terminal hole. There may be another small chip or defect on the side of the lid portion. Sold at Portland Nat'l.
