Hey guys, new to the forum. Just picked up a nice Mk 1 S/N prefix 17-31XXX, 1982. I want to try to buy the correct box for it but have seen yellow and red boxes; 2 piece and folding lid. Can a Mk 1 collector steer me in the right path with perhaps a pic or 2. Ebay has acouple on but I am not sure. Regards, Vanski
