Thanks, bowzart.

I did try to find it in the B&H catalogue, but their mere 2 page "index" for a 466 page tome makes it virtually impossible to find anything. I went to some theatrical supply websites that had it for sale, but I would have to spend anywhere from $50 to $80 to buy it, as I would have to buy a whole box of a dozen or so rolls (I doubt if I would use even one full roll during the remainder of my life).

Anyhoo, Peter De Smidt is sending me a sample piece so I will know what this stuff is that I am looking for. Also, I will call B&H in the phone (with the hope that I will be able to talk to a real human) and see if they have it available in single roll quantity.
