The character of Arnold Feather lost a leg in a letter-bomb blast cliffhanger. Actor Jeff Kevin had to play his scenes, from then on, with a fake "false leg" or wearing long trousers. A year or so later, there were complaints about the actor slowing the action when limping in his scenes. Jeff protested for continuity's sake. The producers said, "Oh, no-one will notice". To his credit, Jeff did keep the limp. Fans do remember seeing Jeff wearing shorts in later years, but this was Arnold Feather's long-lost identical twin, Charles "Chook" Feather.
