WWII Projector Gunsight help

Can anyone help with a Gunsight issue.
I obviously don’t know anything about them. I have a projector Type I MKII Gunsight. Most sights I’ve seen are reflector sights. The part number is 8B/2521. AM Serial No 521/44
It has a single ring for open and shut.
I assume having down some research that is for a night fighter??
Can anyone tell me what this would have been fitted to and the difference between reflector /projector

Welcome to the confusing world of Air Ministry equipment!

What you have there is some flavour of Mk.II Reflector Gunsight. Now the family of Mk.II reflector sights are made up of two parts, a projector and a reflector and the type of Mk.II sight you end up with depends on the combination of the projector and reflector used. Your example is made up of a Type 1 Mk. II projector (missing the bulb housing) and what would appear to be a Type 1 Mk. I reflector. Now I have to admit that I don’t know what type of Mk. II sight this combination would produce but I can say that it’s not the sort of combination you’d want to use in air to air combat and it lacks the tilting mechanism found on the Type 1 Mk.III reflector used with Rocket Projectiles. This would just give you a fixed, un-adjustable aiming point so I’m guessing it would be the sort of combination you may find fitted to an advanced training aircraft.

The graticle is very much different on your one. It does not allow the wing span or range to be set. A projector can project directly onto a windscreen without the need for the reflector top. That said, I have several fitted to the cockpits some say projector some say reflector!
