| X4383 To RHC. {R. H. Coverley - Production Engineer} from EFC. {E. Fowler Clarke - Electrical Engineer} EFC {E. Fowler Clarke - Electrical Engineer} 1/T16.7.23. X. 4383 - 20 H.P. GOSHAWK DYNAMO. Herewith our experimental dynamo which you may remember you fitted with 20 S.W.G. field coils in place of 19 S.W.G., also parallel slot armature handed to us a day or two ago. We would like to have the field coils in the dynamo restored to standard and the necessary fitting carried out (it appears that the spindle requires grinding) to enable either armature to be readily inserted.
