High Geared Back Axle P.III. Confirming our conversation when you were up here last week, we find that we have in the Experimental Dept. one pair of gears 3% higher and one pair of gears 8% higher. We have only one pair each of these types. They were made in America, and there is no tackle in the Works for reproducing them. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} | ||
