That cowl was made by a costumer over in England that went by the name "Goldenage" on the BOTB at one time. I don't think he does costuming anymore. It's a beautiful piece, but as I recall, it had zero neck movement. It was made over a form out of a single piece of mold-able leather. I'm envious of the craftsmanship in it. A gorgeous piece, and great for photos, but would be tough to costume with. Still, I wouldn't turn it down if it was handed to me.
As far as a lining, I'm not sure that I'm going to do one. It looks really striking when the cape is flipped over the shoulders, showing the inside. The look of the backside of the cape, along with the seam work makes for a nice contrast that seems to work well.
