Wor{Arthur Wormald - General Works Manager}4/GR.{George Ratcliffe}1.7.31. Re: Bonnet Ventilators. Sg{Arthur F. Sidgreaves - MD}7/D25.6.31. I understand that a car will be fitted with the modified flip-flap shutters on Friday next. If this promise is adhered to, and these shutters are satisfactory, and approved by Sales, we could start converting bonnets to the flip-flap type within a week after Sales' approval, and it would take us 2/3 weeks to convert the whole of the bonnets for the Show chassis. If, therefore, we can obtain Sales' approval quickly, there does not seem to be any difficulty in our fitting the bonnets with flip-flap shutters before the Works Annual holiday, July 25th.
