Indian Head with moveable mouth

Unusual carved wood head with moveable mouth controlled from behind the long neck. A long piece of horsehair nailed at top of head and cascading down one side. Faceted from chisel marks with dark stain and pigment at eyes.
I have never seen a piece like this and don't know if it was for a ventriloquist or puppet (cloth may have extended down from neck).Looks to be 19th c.
