| To Sg.{Arthur F. Sidgreaves - MD} From Hs.{Lord Ernest Hives - Chair} Handwritten text top left: V7941d Handwritten text right: X 200 V7941d Hs.{Lord Ernest Hives - Chair}1/MJ.18.7.30. 24-EX Replying to Sg{Arthur F. Sidgreaves - MD}9/D16.7.30. This car is fitted with four shutter ventilators - two at the front, and two at the rear. The present standard is two rear shutters only. A Standardisation Sheet has already been sent round recommending that we fit four shutters on the bonnet. As all of our bonnets have shutters it may be called a plain bonnet to distinguish it from a louvred bonnet. HS.{Lord Ernest Hives - Chair} | ||
