I have a bottle that came from Germany that was originally used for battery acid. It does not appear to have a seam mark in the lip. It was purchased in 1961 and was very old then. It is a teardrop shape and I am interested in finding out what it is worth. The only markings on it are a number 25 in the lip and 26L4 on the bottom. I believe the capacity of the bottle is 26 litre.
