We are at present overhauling a Phantom I engine to which we shall fit two of the above manifolds, this car has given trouble in the past owing to failures of the exhaust manifolds this car does excessive mileage and we shall complete same on about the I3th.inst. 2°. We have arranged for Mr. Dubonnet's car 7-AL to be sent to us to have two manifolds fitted we are expecting this car at any time, (therefore up to the time of writing.) We have not had an opportunity of fitting any of these manifolds on cars which we know to do a considerable amount of running, also cars which we can control. Hm{Capt. W. Hallam - Head Repairs}/VA.
