Two pairs of glass flow meters or gauges, from an anesthesia cart I am re-purposing. A picture, it is said, is worth more than a thousand words; please look at the pictures of these objects and regard them as accurate. My description, perhaps less so, but not intentionally; I'm trying, but these are peculiar objects and I am not even sure what they are called.
Nevertheless I can see them as a cool part of a Dieselpunk or Steampunk objèt d'art. They are in good condition and the metal floats slide easily up and down the glass columns.
