Attitude Indicator, 5" Type B-1A Lear USAF SMAMA, F-94, B-50, C-130

$99.50

This is an Attitude Indicator, Type B-1A, made by Lear PN 62160-01 MIL-I-6501A.  It has a service stamp SMAMA (USAF Sacramento Air Materiel Area at McClellan AFB, California) dated Nov 19, 1962. As of 1969, SMAMA managed the logistics support for the F-111A variable sweep-wing fighter, as well as the F-100, F-104, F-105, F-84, F-86, T-28, A-1, T-6, and EC-121 aircraft, and is the repair activity on the F-I06 fighter-interceptor.  We have not been able to identify this instrument as being used in any of these aircraft, but we have found it in the flight manual of the F-94C Starfire Fighter dated 1957, the B-50 Superfortress Bomber dated 1956, and the AC-130A Hercules Gunship dated 1977, see photo of the page from the manual describing its operation. The first flight of the AC-130A wasn't until 1966, so the dates don't support the use of this specific instrument in an AC-130 but possibly earlier versions of the C-130. Measures 5.25in across and ~8.5in deep. 

It is in superb condition given its age.  The dial markings are clear and the glass and case are intact. The rotating horizon requires the right electrical input to turn.
