Chris Volkman Diamond Bottling Works, Eau Claire, Wisconsin
Here is a clear, quart Chris Volkman, Diamond Bottling Works, Eau Claire, WIS. seltzer bottle. In side the diamond, the etching reads, "C.V. (monogram) w/ Trade Mark (in an obtuse angle)" Notice the perforated like etching on the outside of the design. I am guessing that this bottle dates from the early to mid 1910's based on the absence of an etching of the contents.
