For a bit of fun, I offer the following challenge:

What year was this introduced?

Of course the part has to be identified in order to answer the query.

Sorry, no prizes.
This is a ‘vintage’ query – not for ‘Speedies’.
If you think you know, perhaps PM me in order to keep it running for others.

But the strange thing is, I think I know who’s going to tell me.

No takers? Is it really so difficult?

 

Eye of Sauron. The Hobbit was published in 1937 but I'm not expert of Tolkien's bibliography.

 

Sorry but no! There may be magic in this piece but it’s real Omega hardware, no item of fiction.

 

It's a miniaturized Masonic symbol, used as a tie pin for Ken when he takes Barbie to a fancy restaurant!

..... no, wait...... that's not it.

I got it! It's the part of a model of that thing Ben Gates (Nicolas Cage) had to turn to escape the underground vault in National Treasure!

.....ah, that's not it either.

Nevermind.

 

Shape reminds me of a rotor from an old Mazda Wankel engine, but that's not my official guess

 

got it! is a nail head over a plectrum..

 

A blister Mabe pearl over a purple Vick's cough drop?

 

It's a genuine Omega ouija board piece!

 

OK. So it’s a jewel. From an Omega timepiece …

 

Dude, you're spoiling our fun. We don't want the real answer yet!

 

Madonna wore it, clearly. I can't say which concert though.

 

Guitar pick?

 

My guess is that it's a unsharp UFO picture . Like all UFO pictures .

 

Is that how Mazda solve the apex seal problem on the Wankels? Using synthetic rubies?

 

Maybe if Mazda ever produces their long-rumored RX-7 successor, it'll be stamped "21 RUBIS" on the hood?

 

The RX-8 was the successor to the RX-7. Until the problem with emissions can be solved I don't think they will introduce any new rotary engines any time soon.

 

Hamilton caseback from the 60s?

 

STOP THE PRESSES!!!! I've got it - it's a miniature Spirograph cog!

 

I googled that only to realize that as a kid I HAD ONE!
