Extremely rare find. Patent dates on bulb of 1917 and 1918. Bulb and spout have some dry rot/splitting issues. Could use a thorough cleaning to show off details. I did not clean for fear of damaging the instrument and labels. Overall length of ~19 inches. No cracks in glass tubes. One bulb has 'ZEREX, PRESTONE, ALCOHOL' marked on table. Other side has table of 'when thermometer registers' 'the freezing point of solution is' and a label that reads 'NO. 18 - "ZERO-TESTER" FOR TESTING EVEREADY PRESTONE MADE BY E. EDELMANN & CO. IN CHICAGO, U.S.A'

Please ask questions before buying. Thanks and God bless.

Please note - Our home has pets including two German shepherds, a lhasa apso, four cats and 30 fishes.  The fishes and lhasa apso do not shed. The rest of our zoo does. All articles of clothing are stored in lidded bins in our inventory area where pets cannot get to them. Clothing is inspected for and cleaned of any hair before shipment. We may, however, miss some hair somewhere on the piece of clothing. If allergic to cats or dogs, it would be advisable to launder the clothing before wearing or to shop elsewhere.
