| To EY. from DA.{Bernard Day - Chassis Design} c. to BJ. Hs.{Lord Ernest Hives - Chair} X5810 DA{Bernard Day - Chassis Design}1/M23.7.26. " 20 HP. - STEEL ARTILLERY WHEELS. X.4586 X.5810 With further reference to BY/CGH{W Clough}5/H7.7.26., we send herewith N.sch.2240 shewing the original balance weight scheme shewn on N.sch.2048 adapted to the artillery wheels by pressing three bosses equally spaced, with one opposite the valve hole. This seems to come in quite well, and we think is suitable for both the 20 HP. and the 40/50 artillery wheels. DA.{Bernard Day - Chassis Design} | ||
