Hi, Thank you for all your input. The interior of this tunic is black satin like material and it has the white striped sleeves. Their is two interior pockets,one on each side. The outside material of this tunic is what I call a whipwool cord material. I am curious what are the usual outside materials of the tunics you come across are? From what I've collected on foriegn navy tunics and bundesmarine tunics it doesnt have the matching variations. I think that is why it puzzles me.
