I have a number of vintage, wall mounted fire extinguisher/grenades that came with an old house. The patent date of the wall bracket is August 14, 1934. The model number on the glass globe is C-36. I can not determine whether the liquid is Carbon Tetrachloride or Saline water. Does anyone have an answer? I have run out of ways to search. Thank you!
