Does this part belong to a british ww2 plane?

Looks like the same part numbers too!

Mhhh. Loks similiar but i am not sure…

Working on Pogno’s memory jog, are these not the inflation valves from USAAF Mae Wests?

allright, thanks a lot for your help!

It does look a bit like a Safety Pressure Relief Valve of some sort, the steel arm pivots at the top and acts on a sprung plunger inside the barrel of the thing, the arm can be lifted to release pressure manually or it will do it itself if over-pressured, think I have something a bit like it on my central heating.
I cannot think of an aviation use for such a thing unless it is just a valve for draining a fuel/oil tank.
GOOGLE Pressure Safety Valve and look at images, lots of similar.

It does remind me of a car speedo drive rather than being aviation-based.

I may be mistaken but it doesn’t look very aircraft component-like to me – not of particularly good quality. More post war car or other vehicle.

Anon.

Any ideas left?

Too small. The mesure of the bolt is ~13mm

Looks like a tank telescope.

good idea, thank´s! anybody else? my first thought was “part of a gearbox (car)” but perhaps someone can use the numbers….

No idea, but I do have a suggestion. Take a vernier and see if the bolt hexagon conforms to metric, American or BS size.
