Hancock - Head Chateauroux} from Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} 1113 Rm{William Robotham - Chief Engineer}/Gry{Shadwell Grylls}4/R.27.4.37. Thank you for your memo re Bentley rear axle 78-AH. What you say about the propeller shaft damper when solid reducing the period to 30 m.p.h. is exactly what we have always found. If the damper had been set at the correct poundage of about 2 lbs we do not think any period would have been detectable. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} | ||
