Is this a flageleot thingie thing? Maybe with something missing? A honkophone? Poophone? Flutaflute? Flutaflutophone?

I was gonna bid a zillion dollars.
I can’t help it.
I’d bid on charcole if I was in hades.
Anyway. I think maybe they have it turned around backwards or sideways or something…
I’m pretty sure that’s a large leech with external orthopedic fixators. I wouldn’t blow into it if I were you.
You got this dental fixation thingie don’t ya. Or fixadent. Or something.
I’m betting there is a mouthpiece type thing missing. Maybe something you’d put on with fixadent.
Looks like it should be fastened to a sheep’s bladder and be wearing a plaid… 
No VB. I didn’t say orthodontic, I said orthopedic. No obvious teeth on that leech.
It looks a lot like the 19th Century flageolet in illustration 2.2 of The Essential Tin Whislte Toolbox. If it is, then the bulge is supposed to hold a sponge for soaking up condensation, and it may be missing a mouthpiece tip, as the one in the illustration includes a longish ivory mouthpiece, but all combined looks about as long as the one at your link.
That is, most certainly, a flageolette, the predecessor of the modern tinwhistle.
It seems to be a turn of the centuries flageolet, which you can take as a simplified, higher pitched, csakan (these can have many keys which make the look like Northumbrian pipes chanters…).
They’re chromatic (with a trad flute kind of keywork), louder than recorders and change octaves by overblowing. Their bore is conical but less so than baroque recorders.
One blows through an upper or “primary” chamber, located above the duct and fipple plug. In the instrument for sale, the mouthpiece seems to be missing. It’s usually made out of bone or ivory.
The primary air chamber is said to have been the source of inspiration for the NA flutes… In the flageolet, this bell-shape chamber was supposed to contain a sponge to absorb the extra juice.
Often, their cedar block will be too old to play well, but this is relatively easy to fix, since they come off pretty easily.
PS: I’m not sure whether the one for sale is really in C: it looks much shorter (blade to tip) than the Clarke C. My guess is D is more likely.
The model I own, also six holes +4 keys, plays in modern D (though I don’t know if they were intended as Eb for marching bands, with a slower tuning fork). I still suspect it’s D, as a soprano counterpart to the pre-Boehm flutes.
You may have seen this picture, but while looking for the csakan mentioned above I came across this…
What can I say… I don’t know whether this confirms my prejudice on recorders - or gives me a whole new way of looking at them.
Does the tiny woman come with the recorder?
Are you sure that’s a musical instrument? What if there’s a giant Slurpee in there?
Why did you show us a picture of a woman pole vaulting? And cheating at that by using her mouth.
You wouldn’t want to be playing that baby during a lightning storm.
Right–didgeridoos are for sissies. 
Although Mrs Breuking up there (who btw makes fine recorders), proves what counts is not the size of the ship, it’s the wind up in the rigging…
