Referring to the above scheme, would you kindly note that Mr. Royce wishes to simplify the "Goshawk" starting handle as much as possible, and would like you to make the following modifications:- (1) The front cross tube on the chassis should be moved forward about 1.900" until it no longer fouls the starting shaft. The starting shaft bearing can then be a simple double eye [handwritten: shell for clamping] on to the cross tube before the ends are brazed on. By this means a bearing, will be provided which is adjustable in every way except as regards height of centre. (2) The starting handle should be fixed, and not detachable. It should be made in the form of a light drop forging of solid oval section, the lever portion being 7 1/4" long between centres, and the grip being 3 1/4" long. This latter piece should be made of metal tube covered with black celluloid, and the spindle for it should be a simple piece of solid drawn tubing brazed and pinned into the starting handle lever, the grip being held on by the screw tapped into the bore of the tube. (3) The starting shaft should be made of a piece of bar .750" finished diameter, to which the starting handle should be pinned and brazed. [strikethrough: The starting jaw should be screwed on to the thread] [handwritten: The jaw should be provided only by means of a Right hand thread] and the jaw may be detached at any time by twisting it with a spanner in a left hand direction against the starting handle. With this way of carrying the jaw the starting apparatus may be mounted and demounted on the chassis without disturbing the engine. The starting shaft should be drilled up from the front end, as shewn in the sketch. (4) The rear support for the starting shaft, should be made in the form of a sleeve bolted on to the inside of the front cross member, [handwritten: with a taper seat as shewn, the jaw when at rest & the spring should occupy] a position with this.
