Sorry, photos were too large to add directly here. Chx the imgur link below. I was initially thinking it was buffalo but now I'm starting to doubt that. Thanks for the help and any info u can provide.

I think it could be angora goat, also called mohair.

Hi there, Pretty coat. Your second thought was correct. It is a curly lamb shearling coat.
