<html> <body> Jurgen - General question(s): If you're going to the trouble of having these fabricated, are you starting with the best possible materials?  Also, for shapes other than flats, has it been conclusively determined whether horizontal or vertical grain is preferable, or whether the application, or other parameters determine the preference?  Are you planning on supplying only one?  I happen to be about to do dampers on a Mason A, which used, for lack of a better description, M shape felts on the lowest 4 wound bicords.  I've seen these before, and wonder if the design was dropped as ineffective or due to difficulty in manufacturing. I'll measure some and send them if no one else does first.
