| 4555 C. Hs.{Lord Ernest Hives - Chair} C. Ex/HED BY/RD3/ML 24.4.28. 12-EX - DIPPING HEAD LIGHTS - SEC:7004. Owing to the inconvenient position of the hand lever on 12-EX it is proposed to put an extension on to bring it nearer the driver and we send you herewith blueprints of parts required to enable this to be done. Will you please put one set in hand of the following parts to be sent to France to be fitted on the car out there, we suggest that a blueprint of F.78846 accompanies the parts to give the fitter a guide.
