It's only 6" high by about 1 1/2" around. Red label is unreadable, no other marks not even numbers. Was around Carbon Tet parts cleaners for a few years, Solvent was heated to steam also. It just misted down onto parts, still had a small smell. Would not put out much of a fire, Happened to remember the guy was an engineer on coal fired trains and last job was boilers in a factory if that helps. Not pressurized at this time.
