With reference to Aerolite piston shown on EB.4740. We have been working in conjunction with the Light Production Co on the development of this piston, and certain alterations have become desireable for production purposes. (a) The bump on the piston crown is tapered as shown on drawing No.A.2291 for Foundry reasons. (b) The piston rings are chamfered on their inside diameter. Will you please have our detail drawings brought up to date accordingly, and return the following points to Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation} Attached. A.2291.
