Bailey - Chief Engineer} EV.{Ivan Evernden - coachwork} Da.{Bernard Day - Chassis Design}1/HP.26.2.34. Bentley Cycle Type Wings. Referring to N. Sch.3894, wing stays for Cycle Type Wings, the inner stays, bolted to the pivot are intended to be in spring steel. As the coachbuilders have to handle the outer stays and bend them to suit their wing shape, it appears that they will usually be in mild steel, and we therefore suggest that those which we make for bumping should also be in mild steel.
