-Hmm. Looking at what look like precision-machined lugs (with inset, probably spring-loaded, ball bearings to hold it hard against the opposite surfaces) makes me think it is a calibrating, collimating or sighting device for a piece of equipment which requires precise alignment. The viewer peers into the 45 degree-angled mirror to view along the sighting path.
This could be a gun, gun sight or optical equipment alignment tool. It doesn't look like an operational/flying part to me.

-Reminds me of the top of a periscopic sextant, probably an internal component anyway.

-I agree with Anon - looks similar to a Collimator/Sighting/Harmonization/Levelling device,the 6 x Location 'Lugs' look very much like collimator/levelling type mountings/locators.

I had some aviation goodies arrive from an auction house and this was in with it, I've no idea the only wording is R107 it is a prism hand scratched on the rear is the word light. I thought it could come from a gun sight I don't know has anyone any thoughts.
