Crackback label paper

Hello folks,i'm new to this forum and this is my first post and its a want :).Does anyone have any of the old style Fasson crackback paper they'd like to part with for a reasonable price.I'm looking for the old fashioned type paper that had the diagonal brown lines and in a very feint grey it had printed Fsprint cBACK and an illustration showing how to bend the paper to crack the backing paper and next to it ''bend on line''?.Ideally i'm looking for about 50 a4 sheets,but will consider whatever you've got thanks.
Yep its old school alright.Printed a fair bit of that stuff on an old Multilith in my time.Had to get your cylinder pressures right though or you'd run the danger of peeling one away from the other:LOL:
