Is there any further info available about this whistle? Maker, key, etc.?
Is it legitimate?
Maybe, it looks like they sold some used instruments once upon a time as a promotional when they were getting started.
http://www.thecorrs.org/disco/rarities/instruments.html
edit Looking at some of the seller’s other listings it seems they have quite the variety of collectors memorabilia including autographed/signed photos from the Corrs and a massive number of other stuff, so could very well be.
I think it’s not the first time this (or something similar) has been up.
And (added) it isn’t : Andrea Corr and her whistle, old thread
The seller replied to my query on the eThingy and there is no information available about the authenticity. Not even whether its a Feadóg whistle nor key named. Thank you for the old thread. Corr or Picard whistles… I’m just glad I’m not a collector. 
Well, here’s one collector of whistles that won’t be touching that auction with a pole of any length you care to name. I don’t know who “Andrea Corr” is, but is apparently well known. In any event, it looks like you get a random whistle that the seller says was played by this girl. No story, no c.o.a., no signed documentation, you don’t even get the photo that may or may not be of the whistle being sold.
The now ten year old thread already linked to was indeed instructive, as well as humorous. I can see absolutely no reason whatsoever to believe this seller’s fish story, unless he comes up with some evidence.
Cheers
OMG!
You did fill out the questionnaire when you signed up for this forum, didn’t you?
There are very few prerequisites to participate in this forum. A familiarity with Andrea Corr and the effects from playing whistles on speeding motorbikes is one of them, or so I thought.

I sure did! And I thought I made clear at the time I don’t give a fiddler’s fart who the players are – just show me the whistles!!!
Well, we live and we learn! I did go have a listen, though. Lovely playing.
Cheers
Well, O K… just a peek

Now how bout that whistling and I don’t even care what shade of lipstick that is!
But I’m not looking for a scolding today for furthering this… I know my place in the pecking order. 
whistlecollector, please see me after class. You’re looking at 3 days detention unless your 500 word essay is on my desk by 5 PM, entitled “Andrea Corr: Great Whistler or The Greatest Whistler?” I might also accept a mathematical proof of the Doppler Effect instead, if it includes a mathematical proof of Andrea Corr.
Seriously? 
And for the classy folk…
Andrea Corr may be the one whistler that proves the theory that “it’s not about the whistle”. I’ve never seen a five dollar whistle look nor sound quite as nice as one does when she is playing it. Then again I may be blinded a bit, you know, those sisters of hers are fine musicians too. Oh, and there’s a brother you say? Really? Where? 
Nice to end the year with a few of Corrs videos. Thanks, ytliek.

Ya. Maybe “Cute Whistler or The Cutest Whistler”!! 
I think Teacher’s got a crush on Miss Corr! 
One last vid, and yes, its a slow day here… but what I want to know is why there isn’t a prerequisite for whistle performers that when “live” they toss a whistle into the crowd like guitarists flipping picks and drummers tossing sticks. Its only a Feadóg or Gen whistle.

675,685 hits on YouTube and half of them are mine When I started learning Trad someone around here said listen, listen, listen, so… I listen.
Get in line for the AC Crush… where’s SantaC. when I need him.
She can dance too? While she plays!
Ah, but it is a “good” Feadog or Gen. Those are impossible to come by, or so it has been said, on the Internet no less. Has to be true.
And you won’t see any guitarists throwing their Blue Chip picks into the crowd http://shop.bluechippick.net/products/Jazz100-LG.html Depends on the level of the player I suppose. I’d think Rick Nielsen uses a less expensive pick. How many picks has that man thrown into the crowd?

Listening, playing and collecting are three entirely different disciplines. I prefer them in that order.
