Hollingworth} c. to Knagg (Iron Foundry). c. to Wheeler (Alum Foundry). c. to Walker (Pattern Shop) Re/CRS.11/JE.27.3.40. B.40 Engine (75 m/m). The necessary patterns are available for producing the above engine. Will you please produce the castings required to build three units. The following is a list of the patterns. RE.107 (75 m/m) C'case and cylinders. RE.112 (3.50") to produce either bore. RE.109 Cylinder head. RE.108 C'Case - lower half. Other items already issued to the pattern shop are :- RE.132 Exhaust manifold. RE.137 Relief valve casing. RE.152 Rocker cover. RE.159 Induction pipe. 2 Cylinder (Alum) Engine. This is to confirm our recent telephone conversation with SFT{Mr Swift}/EM. that he will check over the patterns for the above engine and let us know how much work is necessary to complete them and how long it will take. A detail list of patterns supplied and returned to Mr. Walker is attached. Re/CRS. | ||
