| DY.{F R Danby} FROM DA.{Bernard Day - Chassis Design} ORIGINAL. C. to Mr. WOT. T. RS.{Sir Henry Royce's Secretary} DA{Bernard Day - Chassis Design}1/29.6.32. X5310. 25HP. HARDY FABRIC COUPLING BEHIND GEARBOX. We send herewith N. sch. 3484. showing the Phantom fabric coupling applied to the rear of the 25HO. gearbox. The object of this is to test the value of a torsionally flexible coupling in this position as regards the elimination of 'Coronation Rattle' etc. It is not expected that it will ever be possible to standardise it.
