| -2- Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}4/MH.{M. Huckerby}29.4.38. (6) B.III Hubs. By.{R.W. Bailey - Chief Engineer} and Da.{Bernard Day - Chassis Design} said that no further alteration would be made to these and it is, therefore, safe to go ahead with the necessary tools and gauges. (7) P.III Propellor Shaft. Da.{Bernard Day - Chassis Design} said he would look into the necessary modifications to the pressed steel cross member, and allow for a ¼" increase in the diameter of the Hardy Spicer propellor shaft. (8) Semi-floating Axle. It was agreed to leave the shaft diameter as shown on the present drawings, namely 1.140 at the root of the splines. By.{R.W. Bailey - Chief Engineer} will instruct the shafts in S.65 material. If at a later date the size of the engine is increased the shaft material can be altered to S.28.
