| -2- casing when ready, in place of the Remy. The Remy would then be carried by an aluminium piece which would fit on to the flange suitable for the R.R. battery ignition. X.2814. Would you also arrange to drive the Remy with a coupling similar in design to the one we have shown on our drawings. We cannot see the reason for the differential selector coupling you have shown on scheme 236, in view of the fact that the Remy cam and rotor are able for the purposes of adjustment to be slipped round on a cone on the driving shaft. The cancelling of this driving piece considerably shortens the attachment which is a great advantage as any- thing projecting backwards from the engine is very objection- able. The camshaft you will observe remains unaltered. An inspection door should be used of a similar pattern to the one shown on our drawings. Further to the forgoing the control gear should be arranged as per LeC.862. I think that you will find that the direction of movement of the various levers applies to the "Falcon" as shown on the aforementioned drawing. E.{Mr Elliott - Chief Engineer} With the exception that the movement of the primary lever on the control shaft appears to be in the opposite direction, owing to possibly the carburetter controls closing differently from the "Eagle".
