Antique Vintage Auto Radiator Tester Edelman & Co "No. 808 FREEZ-D-TECTOR".
precisioneered by Eric Edelmann & Co. (1909) in Chicago, Illinois and produced this product sometime in the 1950/60s. There is no rubber squeeze bulb or hose that attaches to the device. What is shown is in very good condition with some minor rust here and there (see photos). No cracks, chips to the glass portions. The float thing was removed and something red in the bottom of it is dried up. It will ship outside the tester for damage control. Measures 14" L x 3 1/2" x 3 1/2". Weight 1 lb. 4 oz. This tester would make a perfect addition to display in your man cave, gas and oil collection, or vintage garage!
