Herewith we send N. sch. 3156. shewing the actuation of the gears in the three speed box. It also shews the servo and speedometer drives. We think the drawing is self explanatory, and only wish to draw your attention to the fact that the joint between the front and back parts of the gearbox has been moved forward a small amount. Would you please send us a print by return. We may say that the last two drawings - N.schemes 3150/51 - despatched to you on Friday the 17th. inst., prints were only received this morning, causing us great inconvenience.
