| To EY. from Hs.{Lord Ernest Hives - Chair} c. to Sft.{Mr Swift} X8040 Hs{Lord Ernest Hives - Chair}5/LG11.12.25. DIE CAST PISTONS FOR PHANTOM ENGINE. We have tested several of these pistons on an engine on the test bench. If the engine is run up to high speeds, we consider die-cast pistons are quite satisfactory to replace the present sand-cast pistons. Hs.{Lord Ernest Hives - Chair} | ||
