Native american pipe

We received this with my grandmothers things when she died.  it came with a letter stating this was "grandfathers pipe".- this would be my grandmothers grandfather.  grandmother was born in 1898 - so her grandfather would have been born sometime in the early 1800's.  its approximately 10 inches long, in two pieces, the bowl and the stem.  the bowl has some kind of bird claw at the base.  its made of a clay or stone of some kind and the stem is wood.  i don't have a picture yet, but can get one if you need it.

thanks,
