Oh neat! I play an inline, ten hole, Mountain Ocarina. It’s not being produced any more, and it was made only within the past twenty five-ish years (I don’t know that number for sure. Went out of production several years ago too), so you will have a lot of trouble finding one, if at all. And when you do, it will probably be really expensive.
