No, it did not break. I've just never seen anything like the material before. I know someone else who has a dulcimer from the same year with the same nut and bridge. They are different-- her's is a 4-string, and mine is a 6-string. Thanks for the input. Linda

I agree with Ken.  The nut/bridge on my backpacker (DF1) model looks to be made of delrin or a similar hard plastic material.

Did it break?  Do you need to raise/lower the action?  Black & white is probably some sort of phenolic/plastic.

Does anyone know the material of the nut and bridge of a 1994 The Dulcimer Factory mountain dulcimer? They are black on the outside and white on the inside. Thanks so much. Linda
