We are handing to Mr.Tooby a reel of ignition coil secondary wire obtained from McCleod and McCleod of Holborn. Messrs. North have recommended to us that the wire from these people is the best they know of for uniformity of diameter, and we are therefore anxious to have two coils experimentally wound with this wire. Will you please arrange accordingly. HEW. EFC. | ||
