Huckerby} 4.4.39. AXLE FOR 3.B.50. As mentioned to WSC. {W. S. Cassel} yesterday, tests on 2.B.50 have shown that we want a higher axle ratio for French testing and we, therefore, want 11/41 gears in 3.B.50. We believe this helps your position as 11/41's are further advanced than the 10/41. Rm {William Robotham - Chief Engineer} /Gry. {Shadwell Grylls} | ||
