I have removed the packers using the procedure suggested by Malcom and it was quite easy. The soft packers are of a material called hardboard in NZ. It is a dark brown material comprised of wood fibre and glue. It is often found as a cheap backing for wooden cabinets and chests of drawers. The packers were roughly cut and didn't match up with the full length of the aluminum packers. So I have thrown them away and reassembled using only the aluminum.packer. Time will tell if there was an important reason for the soft packers.
