I was surfing around and remembered a company that's in West Va. It is "Panther Primatives". I used to get my primative camping gear for fur-trade era camping called a rendezvous, and thought to myself, "I wonder if they are selling kilts and accessories now?
I looked in their online catalogue, in PDF, and found in the index, that they ifact do carry kilts now! They only have 2 models to choose from as of the 2005 catalogue, and they are very reasonably inexpensive at about $56.00 + shipping. They also carry a dirk and a skian dubh.
Go to Panther Primitives to check it out.
