| To Hs. {Lord Ernest Hives - Chair} from Sg. {Arthur F. Sidgreaves - MD} Sg {Arthur F. Sidgreaves - MD} 4/F30.3.33 - 2 - The question of controllability is not, as you say, anything like as important on the 20/25 as on the P.II and, therefore, this matter can be brought along and dealt with after the scheme has been approved and standardised for P.II.
