The drawing and constructions scheme is proceeding well for the body. It is now settled that DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} will visit several of the likely coachbuilders, and after choosing one or two we will give them all the help we can to make a success of the body. I am satisfied that with the shape and the list of accessories, which include windscreen front and back, metal tonneau cover, disappearing hood, wings, toolboxes, idea of rear end and carrying the spare wheel. At least we should have one completed as we have schemed it, and we are now seeking good constructions for all the parts as far as they are special to this car. ENGINE. The testing of high speed running of this engine (at 3000 r.p.m.) we think has shewn it to be rough. I have decided definitely that we must modify the crankchamber, which will be rather a drastic alteration. In addition, we are lightening the crankpins and webs, conn. rods and pistons.
