As a result of our visit to the Projectile & Engineering Co., and Briggs Bodies, to discuss the problems of pressing the Bentley III. side channel, it has been necessary for us to modify the shape of the rear upsweep in the frame shown on LeC.5741 already issued to you. In order to save time and get the information to you with the minimum of delay, we have altered the original of LeC.5741 and re-issued it to you herewith. Would you kindly arrange to withdraw all existing prints and to issue revised prints. The modification consists of an increase in the radius of the frame upsweep where it passes over the rear axle. No other modification has been made. Att: LeC.5741. E/EV.{Ivan Evernden - coachwork} | ||
