Metal drum with glass circular window at either end, with A shaped glass tube atteched via two red wax coated valves. Glass tube has three glass taps. The drum is copper / brass colured with three sets of ridges where it has been joined together, these ridges each contain perishing rubber. Green discoloration all over body. Two valves run from the body of the cell and attach it to glass tubing - these valves are covered in hard red wax. A glass tube runs from each of these valves and forms an A shaped glass tube system, with three glave valves / taps, one on the tub that joins the two and two more further along the glass tubes, closer to the top of the A shape, where the two tubes join and a short glass tube runs on. The glass tube is discoloured yellow all over, although this is more pronounced in the vlave / tap areas. Some liquid appears to remain in the tubes, though maybe solid as it doesnt flow. Dusty / dirty. Large white luggage tag at end of glass tube.
