Theo. Dietzler & Co. crowns Hartford, Wisconsin

These odd shaped little crowns from "THEO. DIETZLER & CO. HARTFORD, WIS." are embossed in a ring that goes around the bottle (so that you have to turn it to read it). There is a second line below the city that says, "CONTENTS 7 FLUID OZ." The bottles stand around 8 inches tall and are only around 2 inches wide. They were probably made by A B CO as indicated by "S I" hub numbers of "17" & "20". They are slightly bowling pin shaped in that the hub rounds into the bottom.
