A South Indian Jew's harp, an instrument called a morchang, mursing, or morsing. I had a professional tabla player friend buy this for me in 2003 when he went to South India to learn about the morchang. It's a high-quality instrument. The rust has been removed, and it's been oiled and wiped. Made of iron, 117mm in length, key of "E". It has a good volume and a percussive, sharp, metallic sound with a strong attack. I have eight of them, so please comment if you'd like to purchase multiple (the photo is of instrument number 1, key of E). When shipping, I will sandwich it in styrofoam and pack it carefully to prevent the reed from bending.
