I would like to present my latest find in the form of a beautifully preserved battery produced by "Varta" in a glass casing/jar with five cells. Signed "Varta" on the front and 5W and number 441 on the bottom. I think it comes from the turn of the 19th and 20th centuries, if anyone has more information about this type of battery, I will be grateful if you share it with me. Thanks in advance.
