| 600c 800 To HPS.{Horace Percy Smith - Experimental Factory Mgr} Rm{William Robotham - Chief Engineer}/Wym.{G. Harold Whyman - Experimental Manager}5/JH.17.5.39. 2.B.50 and 29.G.VI. We wish to change over the 2 engines in the above cars so that we have the cast iron engine unit B.60 No.2 fitted in 2.B.50. and the Wraith engine W.III No.9 fitted in 29.G.VI. When the cast iron engine is removed from 29.G.VI we want the pistons taking out for examination for knocks Nos. 2,3, and 5, before fitting to 2.B.50. W.III No.9 unit will want fitting up with a standard Wraith induction pipe and Stromberg carburetter. There is no necessity to fit a flexible flywheel to W.III No.9 unit. 29.G.VI. will require a 1.750" dia. tail pipe fitting to the exhaust system. Rm{William Robotham - Chief Engineer}/Wym.{G.
