Unknown flap or airplane aileron

[Wurger]

A question though ... what is a shape of the airfoil seen from the side where the pipe protruding? Is that the symmetrical airfoil (A) or not symmetrical one (B) ?

This looks more like a small aircraft's rudder or elevator to me. Has a torque tube, which is typical for both (and especially elevators), a ground-adjustable tab, and that large rib at the end to me looks like the bottom of a horn-balance.

Example:

Edit: is that big metal rib at the end of the assembly fixed to it or can it rotate independent of the rest of the part?

A small comment about the fasteners. That type nut/fastener was used on our business machines (late 40s through my retirement 1989) and the screw used in them was a blunt tip sheet metal type screw. While sufficient for office machine panels, I'm not sure if they have been used on aircraft panels. From the pictures, they appear to be identical to samples I still have and are U.S. made. Could the flap be from a homebuilt?

Therefore I have asked abot the shape of the airfoil there. Because it may be an aileron as well.

And the metal rib is fixed as you may notice in the pic below.

The only movable piece is the part protruding form the slot between the rib and the flap. IMHO that's a hinge that could be screwed to the rear spar/stringer of the stabilizer/fin or wing.

It can't be excluded,

Thanks for your opinion....here is the add....

There's an old adage in buying collectibles of any type, "buy the item, not the story".

Basically know what you are buying because stories are made up all the time.

Didn't know Germany used Philips screws......

One point more the part is nothing more but the con.

Hi this is my first post ....I have a interesting part flap or more likely an Aileron...? opinions welcome ...It was said to be off of a ME109. Thanks in advance....

With those tinnerman nuts and X head screws in the diamond plate I don't think it's WWII or even German. Not sure what it could be, unless it's from the horizontal tailplane

I think you're right. Thanks for your opinion

Is this electrical wiring? If so, most likely a rudder component. I can't think of any examples of electrical wiring going thru an aileron in WWII.

Yes those are wires....

Where do the wires go? Perhaps Electric Trim or a Tail Light.
