2406 Theo. Dietzler & CO. (low) Hartford, Wisconsin
This is the antique soda from Theodore Dietzler with the word "HARTFORD" written lower on the slug plate. The embossing reads, "THEO. DIETZLER & CO. HARTFORD WIS." There is a "T.D" on the bottom and a very faint mold maker marking of NBBGCO (reverse hub).
