| To RHC. {R. H. Coverley - Production Engineer} From EFC. {E. Fowler Clarke - Electrical Engineer} [Handwritten] X4383 EFC {E. Fowler Clarke - Electrical Engineer} 1/T12.12.23. X.4383 - GOSHAWKAero EngineCodename for 20HP Car / Aero Engine after KestrelAero Engine DYNAMOS. [Handwritten] W610 In accordance with our conversation of this morning, the GoshawkAero EngineCodename for 20HP Car / Aero Engine after KestrelAero Engine B dynamo, for which we previously gave an instruction for it to be put on 3GII instead of No.604 at present thereon, should now be first fitted with one of the two coil per slot armatures which you have prepared, and returned to us for test, previous to going on 3GII. The other dynamo to be fitted with the other armature of this kind is the GoshawkAero EngineCodename for 20HP Car / Aero Engine after KestrelAero Engine E dynamo, but before you fit this, we intend to take an output curve, in order to compare the exact effect on such a curve of this change.
