Will you please put in hand one armature to the prints sent herewith, this is arranged to give a higher output and is composed all of standard parts but wound with thicker wire, it will be therefore necessary to mill the slots in the core to suit (D.51626), make a sets of coils (D.51628) with .048 D.C.C. wire of which we have plenty in stock.
