The design of the mechanics to take up wear are different on the two microscopes. The direction of adjustment as well as the type of screw changed as time went on. The earlier model used blackened slotted steel screws. The later version used lacquered brass screws with holes on the sides of the heads. A strong metal rod of the correct diameter is required to adjust these.
