Free Air Temperature Indicator, Direct Reading, Type C-13A WWII

$34.50

This is an authentic vintage Direct Reading Free Air Temperature Indicator Type C-13A, as used in Bombers Boeing B-17 Flying Fortress and Consolidated B-24 Liberator, plus Transport Douglas C-47 Skytrain and others. The instrument indicated to the pilot the aircraft's external air temperature from -60dC to +50dC in aircraft of the Air Force US Army, and would have its stem installed from the cockpit or the bombardier's compartment thru the skin or the windshield of the aircraft.

Most uniquely, this instrument has the letters embossed on its face "A.F. U.S. ARMY", which stands for Air Forces US Army(difficult to see in photos). The Air Force US Army was the predecessor to the US Air Force.

It is in good condition given its age. The dial markings are clear and the glass intact. The temp reading may not be accurate, nonetheless it is a nice artifact of the era. Measures 2in diameter and 5.5in long. See photos.
