      I have an aircraft wing roll gyro from ~1953. I want to hook it up
and get it working. There is no information about it except that it was
built to "ordinance #9064932". There is no manufacturer or part number
on it.
      I talked to some gyro experts at Honeywell and they gave me some 
good historical info, but couldn't help locating the spec sheet.
Apparently the "ordinance number" was a government spec that was
issued for military and governement equipment before the current system
of "national stock numbers" was created in the late 1950's.
The gyro experts also told me that it most probably uses a 24V 400Hz
power, as did all aircraft equipment in those days.
      The gyro has about 6 wires. I checked continuity and resistance
across all combinations of the wires, and some of them have resistance
in the 3 to 20 ohm range. These probably go to the windings of the motor
or inductive feedback sensor. I'm afraid to hook up 24V power to it
because I don't want to accidentally burn out a sensor.

Does anybody know wgere I can locate a spec sheet for this gyro?
