Medford Bottling Wks. (Varrient)

Embossed on the bottle is the following: "MEDFORD BOTTLING WKS., CONTENTS 7 FLD. OZ."

Here's a nice variant from this bottler, an ABM CROWN TOP-1/2 PINT (7 OZ.)-AQUA-CIRCULAR PLATE MOLD EMBOSSED SODA BOTTLE, with "21 S 1" on the heel which means this bottle dates to circa 1921.
