Capt. Robert A. Lewis' Original Computer: true airspeed circular dial AC Type G-1 manufactured by Crowe Name plate & MFG Co, Chicago, [issued and used July/August 1945]

Computational airspeed disc, with two discs and a plastic pointer arm, in its original card board package as issued.
Provenance: Robert A. Lewis, co-Pilot, Enola Gay, 6 August 1945; and then as a gift to Steven K. Lewis.

An almost mint airspeed dial belonging to Robert Lewis and used on the Hiroshima bombing mission. It was likely issued to him when he got to Tinian as part of the equipping of the Enola Gay. This was a standard piece of equipment issued by the USAAF to all Navigators and Pilots and was essential for working out true airspeeds, taking into account the head, tail and side winds. Family tradition and Lewis's own testament to his family places this instrument in the Enola Gay on August 6th, 1945.
Diameter 8 in (205 mm) (1)
