Draper - Frames} Ev.{Ivan Evernden - coachwork}1/JH/1.7.40. re Specification of Silver Ripplet Production Model. Attached herewith are 3 copies of the specification for the Silver Ripplet Production model PL.254, 1 set of prints is for Oy. 1 for Ashby and 1 for Rm{William Robotham - Chief Engineer}/HH. This specification represents how we would build the Silver Ripplet for immediate production. In this specification we have incorporated as far as possible only parts which have done some running. Where parts gave been run and have also been found to be unsatisfactory we have included an improved design which is likely to be satisfactory. This production Silver Ripplet forms the basis of all production models of the 6 cyl. cars in the Senior Rationalised range. The experimental example of this car as Silver Ripplet 2.R.2. for which there is a specification.
