On a recent excursion I found this clear hobnail bottle that is different from any other bottles in my collection. Most of the time I only find these bottles in pieces. It is about 6 5/8 inches tall and has the Owens-Illinois diamond and O entwined with an I in center. To the left of it is a 7 and on the right a 9. Date codes for Owens-Illinois bottles tend to be to the right of the logo. Single digits are usually from the 30's. So I will estimate it to be 1939. Does anyone know what brand or product was in this bottle?
