There seems some doubt as to what this car should be.

It should be the same as 2.B.50 except for the necessarily longer pieces and

Front apron - being drawn by Ev. {Ivan Evernden - coachwork}
Front buffers - DB. {Donald Bastow - Suspensions}
Steering column - PD.188
Dashboard - up to Ev. {Ivan Evernden - coachwork}
Radiator & Bonnet - R.R. shape.

As regards O Dept. the gearbox should have standard ratios and small cones. The axle of suitable track with the old type tube should be 9/37 ratio, 45 mm half shaft and Timken bearings.

An index sheet is required from E Dept.

when first built this car will have an existing Wraith III engine. It will later be changed for a B.60 unit. Instructions for the unit and its mounting will follow.
