I recently found this great bottle at an estate that had been owned by the same family for over 80 years. I would like to find out if it is an 1800's original or a reproduction, and if it has any value and what the value might be. It measures about 11 1/2" tall and is embossed near one eye with "DOCTOR FISCH'S BITTERS" and under the other eye with "W H WARE PATENTED 1866". The bottom is unmarked but shows a thin indented line (possibly a straw mark?). It has a flattened long oval section on one side along the fish's underbelly. There is a mold line that runs up the sides and looks like it stops at the neck. When you look at the glass in the light it looks wavey or grainy inside.
