Sorry, no. But the thing does cover something.

Is it part of the locking mechanism on a lens cap?

Yes, it is! It is a "reverse" of a Tamron lens cap.



Well done! Over to you.

[menace1944]

Here is another one. Nothing to do with photography but should be easy.

A hole punch perhaps?

Thanks Dennis, ah it's only because I'm office bound (most of the time) and occasionally work with paper

I'll have a quick think and hopefully put an image later this evening

[Greytop]

OK here goes.
A little clue to start off, this moves amazingly fast....

[Fast Eddie]

grinding disc (attachment for a drill)?

[Greytop]

Good guess Eddie, I can see why you might think that but it's not a grinding disc.

Edit: Without hopefully giving too much away the fast motion is over very short distances.

Is it part of a bicycle wheel showing the tyre. John

Hello John, I can see the similarity with a wheel rim and tyre but no I'm afraid it's a fair bit smaller than that. Good guess though

[Fast Eddie]

wind up car?

Afraid not Eddie but you're in the right ball park for the size but not the motion.
Think about another type of motion rather than rotary, there you go... slipped in another clue

[Greytop]

Here's another image, narrow DOF but your imagination will join the dots (that's not a clue btw)

The next clue is... cycles per second.
