| X8664 [RECD?] C. EFC. BY/RD6/ML9.5.28. RE 40/50 CHASSIS - DYNAMO ARMATURE - SEC:8070. R2/M.18.4.28. Will you please put in hand one armature to the prints sent herewith, this is arranged to give a higher output and is composed of standard parts but wound with thicker wire, it will be therefore necessary to mill the slots in the core to suit (D.71618), make a set of coils (D.71620) with .056 D.C.C. wire. I do not think we have this size in stock and 2 1/4 lbs. will be needed. Prints:- D.71618 - Armature Arrgt. D.71618 - " L.O.P. D.71620 - " Coil. BY/RD. | ||
