We are sending out to you in the care of F.Dodd a new dynamo fitted with a special experimental grade of brushes which have been carefully bedded down and measured. Will you please arrange to change over the dynamos on the Bensport at the earliest possible opportunity, noting the speedometer reading for us. The new grade of brushes is designed to cut down to a minimum the excessive wear experienced on the last 10,000 mile test. We should be glad if you will carefully note any brush noise or irregularity from the dynamo. Hs{Lord Ernest Hives - Chair}/Wst. | ||
