I bought a job lot of items from a mate who does house clearances yesterday. One of items was this mystery object. I've checked it all over for markings and all I could find was that each major item in its construction is stamped with a number 5.
It looks like an gunnery director to me but I can't find anything similar on line.

Any help with an ID would be appreciated
Cheers
