Coverley - Production Engineer} HPS.{Horace Percy Smith - Experimental Factory Mgr} (ST) Holden Rm{William Robotham - Chief Engineer} / SD Re Phantom III Bonnets. As promised to you yesterday when you were in Derby, we send you herewith a print of the Phantom III new standard 11° slope bonnet side plate on which has been drawn the standard 25/30 H.P. bonnet 11° shutters. As explained to you, if it could be agreed that these shutters could be used on the Phantom III bonnet the present difficulties which the Works are experiencing in producing the new standard Phantom III bonnet would be largely overcome. No tools are available at the moment for the 11° Phantom III shutter. An early decision on this matter will enable the production of the bonnets to go ahead. Ev.{Ivan Evernden - coachwork} | ||
