Hi to All,
I can say that back in the early 1960's, (in my opinion) that they didn't have cork with a peel off backing, used in their clutches....I believe that it used a very thin smear of contact cement to secure the cork lining. This is what I have used in my Scotty 45, and has worked a treat for over 25 years....As I have said, this is just my opinion.
