| To HY. {Tom Haldenby - Plant Engineer} from EFC. {E. Fowler Clarke - Electrical Engineer} c. EY/RD. c. EP. {G. Eric Platford - Chief Quality Engineer} X4383 EFC {E. Fowler Clarke - Electrical Engineer} 3/T1212.23. HH1D X. 4383 - FIELD FUSE FOR GOSHAWKAero EngineCodename for 20HP Car / Aero Engine after KestrelAero Engine. & E.A.C. X. 2515. As explained to you in conversation, we now have very definite evidence that technically speaking a field fuse of 40 S.W.G. copper is most desirable. We have run field fuses of this gauge in connection with GoshawkAero EngineCodename for 20HP Car / Aero Engine after KestrelAero Engine dynamos for an aggregate mileage of 10,000 on one or two experimental cars. Before issuing a standardisation sheet, however, we would like you to consider what arrangements should be made to make these fuses most practically satisfactory from the customers' point of view, seeing that we shall then have two sizes of fuse wire and that it would be desirable to have a different type of fuse holder for this particular fuse.
