Along with "Period Correct" goes "Period Terrifying". Isn't that part of the vintage bicycle experience? There is virtually no difference between mathauser and koolstop; koolstop manufactured the pads sold by mathauser.
I and several people on this list draw the line at safety items like brake pads, cables, tire rubber, etc., and upgrade (on riders) to the finest stuff available today to extend our lives on the road (and reduce our bills in the hospital ...) I find that modern lined cables and koolstop salmon pads/holders can do wonders for vintage brake systems. They also look great on weinmann(salmon) or campy(black) brakes!
