If when you smoke it, it has a taste of dead animal, it’s bone. If it has the smell of burning hair, it’s tusk or ivory. I had to cut up some ivory for a customer once, and the saw heated the material and everyone had to evacuate my store, ha ha. One customer was a fireman and he told me that it triggered having to pull burned bodies out of a fire. To me it smelled like burnt hair. I was going to make a pipe from bone, but heated, it was awful, like rotted corpse. I did make a stem from the bone, but it was so porous that it turned dark brown with sticky tar. Nasty stuff.
I’m not sure what metal the figure is made of on the brass. With the focus of the picture, it looks like it is pressed lead or epoxy, but it’s most likely pewter.
As for it being an Eskimo or Inuit, they are on top of the world, geographically speaking, but other than that, I have no idea.
It’s a beautiful pipe though. I hope it’s meerschaum.
May it bring you many fine smokes.
