Knee pad rubbers, Norton 2 hole (pr)

Norton kneepad scripted rubbers - 2 hole (pr). Suit Nortons 1949? to 1955? NOTE: These pads have the Holes closer together than originals.  You can make an extra top hole and fill the existing hole with a grommet or black silicone. I have done this on my ES2 for these pads.  The  hole centres should be close to 4.75inches. These copy pads have the hole centres at 4.5inches with the bottom hole being in the correct position but with the top hole too close together.]
