ORIGINAL X8000 X1476 [STAMP: RECEIVED DEC 2 1927 HS{Lord Ernest Hives - Chair}] It will be realised that it is of the utmost importance to get the strongest and lightest castings in aluminium, for crankchambers, etc. I understand that we are persevering to get: (1) Hall light alloy (aluminium-magnesium) or something equal. (2) Die-castings where-ever possible. (3) Use of aluminium bronze because it is stronger than other bronzes, and can be die-cast. I did hear that (3) was not used because it was difficult to machine, but there should be no change from the instructions without permission from the designers and testing engineers, because of the loss of strength.
