| Da. {Bernard Day - Chassis Design} 14/G.27.3.39. Allocated to Da {Bernard Day - Chassis Design} /EV. {Ivan Evernden - coachwork} RADIATORS. There are three radiators to be done for models in progress and being instructed viz. 'Ripple', B.50-RR., and 'Cresta'. With the radiator has to be done the lamps, horns, wing stays and apron. As appearance is involved, Ev {Ivan Evernden - coachwork} 's Department is dealing with these radiators etc. It will probably take three weeks to instruct the first two, and five weeks for "Cresta". It is then proposed that all the radiators done should be reviewed, with a view to reducing pieces to a minimum. This probably will not take long, say two weeks additional to above.
