Honeyman - Retail orders}/Rm.{William Robotham - Chief Engineer} 637 E/HDY.{William Hardy}1/MN.13.7.36. Wraith II. Holes in the Frame Cross for the Propeller Shaft. N.Sch.4854 herewith shows the above. These holes should be instructed in the first frames ordered, as it is unlikely that holes any smaller than those we show would be adequate. When dismantling the gearbox the propeller shaft must be disconnected at both ends and removed from the cross in order to allow the gearbox to move back the 4" necessary to clear the engine before dropping down at the front end.
