| Y 4 5 5 3. To BT.{Capt. J. S. Burt - Engineer} from E.{Mr Elliott - Chief Engineer} E.1/HP.12.1.33. c.c. Mr. Her. Hs.{Lord Ernest Hives - Chair} Hr. 1st Experimental Bensport Chassis. ---------------------------- The following is the list of drawings that have been issued in producing the first experimental Bensport with the existing engine unit, and 20/25 gearbox. Those drawings marked with an asterisk are directly applicable to the final Bensport design. Some of the remainder are also applicable but require going over to ensure that they represent the best solution for production, as in some cases we have used in existing material which we know will be modified, such as the dampers with two point mountings. Some of the drawings apply only to adaption of the 20/25 gearbox and will be washed out when the final design of gearbox is fitted. *Lec.3256 - Crankcase Rear End. 3258 - Expl.
