| -2- Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation}1/JH.1.4.40. Category 'C' Cont'd.{John DeLooze - Company Secretary} B.80 No.8 (3.25 bore) Alum construction. B.60 No.12 (3.50) Test Bed. Wilcox Rich Tappet Note. B.60 No.10 should be built from any up-to-date parts from B.60 No. 7. B.60 No.12 Existing pattern which is part modified should be completed to produce this. It will be noted that this arrangement enables existing and new chassis to be fitted with the latest rationalised units as they become available, at the same time using up existing material where possible. Regarding the eight cylinder unit, it will be noted that only one more engine is at present required, namely the "Alum 8". As the patterns for this are still only part finished, they should now be completed to the latest specification for the eight cylinder engine. All engine pieces in progress in the shop which are not now required to complete this re-arrangement should be stored for use later for possible marine development. The engines to which we refer which are not now required as complete units but parts of which should be stored are as follows :- B.60 No.7. B.60 No.11. B.80 No.6. B.80 No.9. B.80 No.10. B.80 No.11.
