| ORIGINAL BY. {R.W. Bailey - Chief Engineer} (crossed out) FROM DA. {Bernard Day - Chassis Design} SECRET DA {Bernard Day - Chassis Design} 1/M23.2.29. C. to SG. {Arthur F. Sidgreaves - MD} (crossed out) HS. {Lord Ernest Hives - Chair} RADIATOR SHUTTERS. X3499 X7250 (crossed out) With reference to the complaint of the too rapid opening of the shutters initially, we believe Derby are experimentally determining the most suitable arrangement of levers. In case not, however, we send herewith N. scheme 2837. shewing how by very slight changes the initial shutter movement can be reduced to one third the present amount. It is intended as a suggestion as to the direction of improvement. It may be found that slightly less improvement will do. DA. {Bernard Day - Chassis Design} | ||
