This lovely cruet was manufactured by the Cambridge Glass Company. The pattern is called Diane, and was made from 1932-1956. This is a cruet or salad dressing/oil bottle. But I have searched extensively, and can not locate this exact piece. It is marked on the base with the Cambridge mark - C inside a triangle. It stands 8.375" tall with the stopper. The stopper is original to the piece. There is a very tiny flea bite on the stopper as you can see in the photos...
