| E.{Mr Elliott - Chief Engineer} FROM DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} X6135 DA{Bernard Day - Chassis Design}/EV{Ivan Evernden - coachwork}1/M.13.1.32. C. to SG.{Arthur F. Sidgreaves - MD} WOR.{Arthur Wormald - General Works Manager} HS.{Lord Ernest Hives - Chair} BY.{R.W. Bailey - Chief Engineer} J.{Mr Johnson W.M.} 3. INSTRUMENT BOARD. The initial proposal for the instrument board on J.3. we understand is to have a central patch with a RR switch in the middle. The instruments would all come from one source, and the patch be made by the instrument makers. Our switch would be made to go into it. With aview to sketching what we propose we would welcome either models of the instruments proposed to be used, or a drawing shewing same. We shew below a sketch of the proposal. We understand the starter carburetter control is on the column. DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} | ||
