Featured Help ID Tribal Rattle/Whistle ?

Found at a garage sale in Portland,OR on a table w/ repro & fantasy pre-Columbian ceramics. It caught my eye because of perceived (???) age-of course 99.9999% of theses artifacts are phony.
Polychrome surface seems to have age wear,cracking shows signs of glue,2 holes on base-with a large pea-size free rolling ball inside.Degradation of base glaze clay poss long-term ground contact ?
Shaken it makes a rattling sound-no sound when I blow on either of the large holes or the mouth slit.
Size- 7 1/2" lngth X 4 3/4" wdth X 3 1/4" ht.
Any opinions or info welcome-thanks !
PS- Will be hitting garage sales for nxt 3-5 hrs, sorry if incommunicado.

 

It looks promising. Probably from Costa Rica. Here is a similar one in the Met -

The deterioration on the bottom looks similar to conditions I have seen on genuinely old pieces - more than simple shelf wear.

 

Another example that shows the typical colors of Costa Rican pieces -

Thanks @2manybooks- ditto,Costa Rica was the only country of origin I could find for turtle rattles/ocarinas that didn't have much in the way of feet.
I never buy these pieces, but this one was suspiciously authentic-looking.
PS- Will shoot some pics to museums & auction houses. Note, even if authentic-not a priceless item, but just finding the real thing'd be a kick !

 

Good find Bosko--- I think it looks promising too.

 

Promising and charming. Always love that colour combination.

 

Good fer yew, Bosko!

 

I don't see how that's a whistle..?

 

Some of them are just rattles.

 

wouldn't the stones fall out of this one?

 

Maybe the crack in the shell prevents successful whistling by letting air escape instead of going all the way through?

It's a wonderfully well observed turtle face.

 

Thanks for all the observations-quite a unique find for me ! Can't recall ever finding a possible piece of classical excavated (burial ?) archaeology at a garage sale before-never anything this obvious at least.
@2manybooks -Yep, think it's a rattle (not whistle)
@komokwa - Will post an illuminated pic of the interior,and you'll see how big the ball is (lks more like a fired ball of clay than a stone).The ball was placed inside the the body before it was sealed, painted and finally fired.
@Bronwen -ditto, love the face.
Here's a pic I just shot of the interior w/ the ball (that 'rattles' round).

 

Wot a clevious fellow!

 

Some modern whistles have a ball inside, & this looks like it has the hole you can put your thumb over to change the pitch. Maybe it also served as a rattle , but I think whistle too. Maybe a pre-Columbian one-man band.

 

Doesn't it have two holes in the belly, one near the head and one near the tail?

 

Yep AJ- 2 holes,a head and tail one.
"Pre-Columbian Costa Rican ceramic whistles & rattles (ca. 800–1525 A.D.) frm regions like Línea Vieja & the Diquís) are ancient clay instruments shaped like animals or humans. They served sacred ceremonial duties, shamanic rituals, or status expression, containing small loose clay pellets to rattle alongside air ducts to whistle." -The Met Museum.
Seems some were combo instruments (whistle & rattle), and some may have been single-purpose (whistle OR rattle) I think ?
The Artisans appear to have had a fair amount of freedom in fashioning these little pieces.
