18) An interesting original heavy gyroscope part. The only marking on this is the Nazi eagle which looks to be an early form. This was purchased by us as being from a V1 Doddle Bug which crashed in the Southampton area. A little research shows it as being more likely from a torpedo or similar? . It is a good weighty lump of bronze/brass and spins nicely. it measures 3 1/2 inches across. Any info on this item would be much appreciated.
