| contd:- -2- and on the cars referred to, this mechanism did not exist and had either never been fixed or discarded. Probably Hs.{Lord Ernest Hives - Chair} will be able to confirm such experience with cars on test fitted with this type of cut-out as I believe, in those days, he was personally testing such cars. We also have the impression that the difference in exhaust noises between this cut-out being open and closed was very little, and as it was not appreciated by customers, was certainly not made use of. The suggested improvement of this scheme, however, for the exhaust gases to be thrown out of the back of the car, is certainly a very important point. Lubrication of make and break cam. We will attempt to embody Mr. Elliott's oiling device on 7-Goshawk-11. Oil consumption, filter gauze. Coarser gauze for the filter is the actual standard at present and is fitted to 5/6/7-Goshawk-11 Bonnet supports. We have attempted to do without the rivets on 6-Goshawk-11 but on 7-Goshawk-11 we are attempting to fix the fabric material so that the hinges will rest on the fabric and not have metal to metal contact. Slots in Undershield. 6-Goshawk-11 is fixed up with a guard to the exhaust hole in the undershield through which the exhaust pipe passes, but not the pendulum lever which has not so far been reported on, but Hy.{Tom Haldenby - Plant Engineer} reports that this also appears to require protection and we will fix some protection on 7-Goshawk-11 as you propose. Heat from engine, bonnet louvres. Is it proposed to have any louvre scheme at all for the first production of Goshawk-11, or is it proposed to apply blanking plates as was done for the 40/50 chassis?
