Pitot Tube Type D-1, 369D-012
This is a WWII-era Pitot Tube, Type D-1 (also AN5816-2), as used by aircraft of the US Army Air Force and US Navy, such as bombers B-24 Liberator, B-25 Mitchell, B-26 Marauder, and A-26 Invader, fighters P-39 Airacobra, P-40 Warhawk, and P-47 Thunderbolt, dive bomber SBD Dauntless, and torpedo bomber TBM Avenger (see illustration from the TBM Erection and Maintenance Manual dated 1944). On most bombers, this pitot tube would be mounted on a stanchion on a side of the fuselage, and on fighters, mounted on the wing. This example is made by Kollsman, part number 369D-012.
This pitot tube is clearly experienced, but a very nice artifact nonetheless. Measures 13 inches long.
