Gates Stat-Test 5900. Use to test condition of thermostat and make sure it is opening and closing properly per the directions state. Can be displayed in your showcase, on your shelves or in your radiator cap opening. I am not sure of the date but guessing somewhere in the late 50's to mid 60's. Very nice original case and tester. $50 plus the ride.
