| P.J. Harely. Agreed? 341 E.1/HP.30.1.37. ~~BY.{R.W. Bailey - Chief Engineer}~~ c. ~~Rm.{William Robotham - Chief Engineer} RHC.{R. H. Coverley - Production Engineer} Da.{Bernard Day - Chassis Design} Hdy.{William Hardy}~~ Phantom III - 25/30, abd Bentley Servo Motor. - Sec.6180. In connection with N.Sch.4283 servo for semi-servo system Phantom III, and N.Sch.3927, outboard bearing 20/25 and Bentley, we note that piece number G.82763 ball bearing housing - 1 off Phantom III, and G.56558 ball bearing housing- 1 off 25/30 and Bentley are identical except for the 1.150" diameter. x .050 proud projection on G.56558. It appears to us one of these pieces could be used on all cars, and if you are in agreement we should like to arrange to use G.82763 on the 25/30 and Bentley chassis in addition to the Phantom III. Both pieces are produced from the same forging. We attach herewith blueprints of the details G.56558 and G.82763. ATT: E.{Mr Elliott - Chief Engineer} | ||
