content: Submarine Telegraph Muirhead Transmitter Gears. A box of four brass gears used for a Muirhead submarine telegraph transmitter. Gears are stamped: "C", "G 6/10", "G 6/10", "C", respectively. Two of the original six gears are missing. The two marked "C" do not fit the recessed holes, so are probably not original to the kit.. Penciled inside box: "3 Centre / Holes", "^ Centre / Holes", 1.12", "1 1/4", 2 1/2", ".5". Stamped on bottom: "69547" and "12". Four small steel wrenches are included although no recessed slots are cut into the box to house them.
