I found it listed in the Ohio milk book at $15.00 to $20.00 but take that with a grain of salt its a cheater book. Over half the milks in the book go daily for at least 3 times there estimate. Maybe someone closer to Napolean will know something.
Good luck in your effort. Sometimes these old posts revive interest. Also welcome to Antique Bottles. Collect what you like. Like what you collect. Remember that bottles are just stuff. The true treasure is not bottles, but friends. Hope you acquire many. This is a good place to find them.
