Hello! I am looking for some help in regards to this bottle. I am unable to find anything in regards to the embossed logo. It does have "D.O.C 313" towards the bottom as well as "Reg US Pat 1907". The actual bottom of the bottle is clear with no markings. Based upon research, it appears this may be a Dominick O Cunningham Glass Co bottle and probably produced between 1890-1920. It's 10" tall. Any help would be greatly appreciated...thank you!
