12" tall & 10" bit so it's huge.

I don't for one minute believe there is any connection whatsoever between this head, your Indian head & the O.Ps axe head. Other than they are axes that share a shape.
There are millions of axe heads, being a similar shape is just .....well... a similar shape, nothing more (yes, we know there are historical styles & patterns, but these don't have common ancestry).
On the forum I linked to people post up found axes with expectations after seeing an image online that's "similar", most often it turns out to be something different. Have a look through the posts yourself.
