| RHC.{R. H. Coverley - Production Engineer} From Ha/Wst. Ha/Wst.3/MA.12.8.35. BATTERY IGNITION DYNAMO. We have asked under cover of our Ha/Wst.2/WJ.29.6.35., for a new armature shaft and commutator to be produced for the above. Will you please have a new armature produced for us using this shaft and commutator and new armature plates which we have obtained to our drawing EL141. The winding should consist of 6 turns per coil of 21 S.W.G. Enamelled paper covered wire (which we are obtaining from Messrs.Concordia), two coils per slot. As our tests on this battery ignition dynamo have now been held up some time, we should be glad if you will urge the completion of the same. Ha/Wst. | ||
