We are told that the "V1 gyro" from Ringinglow is actually a Sperry gyropilot as illustrated in this pic from the manual. They were apparently fitted to C47s and early B17s.
But others claim it is a GA VIII Gyroscope from a WW2 German G7e torpedo. The torpedo gyro pic below (from German Wapedia) looks pretty convincing to my inexpert eye, there are so many points of similarity that this must be it, or a very close relative.So who missed the sea by 100 miles?
