In the mid 70's, I spent the summer in a house on Orange Street on Nantucket. I found this bottle in the attic. It's made of dark green glass and, at the time, had a somewhat soiled label on it. Sadly, I promptly washed it off then, and can't remember what it said. The bottle seems to have a taper top, and the body is in three sections; the round body, with two halves of the neck together on top (there is a vertical seam running up the neck from the horizontal joint). Quite a few small bubbles are trapped in the glass. The base says "CB & Co" with an "N" under it. In the photo you can see a large piece of cork still inside. Can anyone venture a guess as to age and type? Many thanks
