| To BY.{R.W. Bailey - Chief Engineer} from DA{Bernard Day - Chassis Design}/STT c. to EFC. X.4195 DA{Bernard Day - Chassis Design}/STT2/AH9.11.20. ARMOURED CARS -------------- We send you herewith modified drawing "N" Scheme 621 in connection with Towing Hooks on Armoured Cars. We have increased both thickness and depth of these hooks, but we have not altered the fixings as they are still stronger than the hooks. This is to confirm that if the W.O. press for these hooks very strongly you may agree to the strengthened hook herein shewn, but, otherwise, you prefer to go on as at present owing to these hooks being nearly completed by the works.
