Attitude Gyro Horizon Indicator, Sperry 672740 H-5 Type COMFAIR JAPAN

$95.00

This is a 1950's-era Attitude Gyro Horizon Indicator as used in the US Navy/Marine Corps Fighter Jet Grumman F9F-5 Cougar and the HUP-1,-3 Helicopter, made by Sperry PN 672740 as a "fast-erecting" gyro (as it fast as it could be in the early 1950's). It also has the USN stock # of R88-I-1331, linking it to the F9F-5 as seen in the F9F Flight Manual (see photo of page from manual dated 1955). The gyro was also named as a Type H-5, but is not labeled as such. In the photo gallery, see the illustrations of the location of this gyro on the instrument panels of the F9F-5 and the HUP-1 from their flight manuals.

This example has a service label and yellow stamp (dated Oct 1954) from "Com Fair Japan" or "Commander Fleet Air, Japan", which was the name of the command at the US Navy air base at Atsugi, Japan from 1950 to 1964. 

The knob adjusts the indexing 'aircraft' within the dial to align the perspective of the pilot to the horizon indicator. It is in terrific shape for its age. The glass and case are intact and the dial markings are clear and precise. The horizon sphere rotates freely, but requires the correct electrical input to function properly.  Measures ~3.5 inches diameter and ~8 inches long. Would be a very nice addition to your collection.
