Drapers is a distributor, not a manufacturer. They do have a book called Blazon. The fabric in that book is made by Vitale Barberis Canonico, and it is Super 140s. I don't believe that it is a particularly vintage book, but I may be wrong. I don't have any specific experience with it, but Drapers stuff is generally pretty good. Some people seem to think less of VBC stuff, but they make some pretty good fabric for Drapers.
