Roy.{Sir Henry Royce} Rm{William Robotham - Chief Engineer}/Std.8/AP.22.3.38 PH.III. HIGH SPEED FANS. You will recollect that approximately a year ago we supplied in all twelve Ph.III. 5 blade fans and high speed drive sets for fitting to customers' cars in cases of idling overheating complaints. We have not heard any request for spare belts for these fans, but in case such are needed, would point out that these are not identical with the standard belt, being larger in section. The Belts in question were obtained from Messrs British Goodrich to their Mould No.242 and if required, replacements can be obtained from the same source. When ordering, however, it should be specified that belts black in colour are required. Rm{William Robotham - Chief Engineer}/Std. | ||
