For attention of W.A.Robotham, Esq., Messrs.Rolls-Royce, Ltd., Expl.Dept. Derby. Dear Sirs, There is one point which we omitted to modify in the two experimental gauge heads recently returned to you, namely, the increase of the threaded portion for the "pinch" screw holding the armoured sheath at the front end of the air lines. In case the car has not left your works on its test, we are enclosing a modified support for fixing to one of the gauges. On this we have brazed a boss, so as to give a greater portion of threaded portion. We believe that this would be an easier fixing at the back of the facia board, than having to introduce a small bolt and nut. We do not think it would shake loose, as | ||
