Mark II Reflector Sights and Type I Mk. I Projectors
Have most of the variants. Still looking for the earlier version of the tilting head for the Mark II and the elusive Type I Mk. III Projector.
Mk. III Reflector Sights
By far the most mass produced British aircraft gunsight. Easy to find today, at least for the Mk IIIA version.Gyroscopic Gunsight Mk. IC Gyroscopic Gunsight Mk. IID
Have five of them (should stop buying) from N.O.S. to in need of complete restoration.
