Hs{Lord Ernest Hives - Chair}/AFM.{Anthony F. Martindale}14/KW.31.1.36.

When you were over here I saw Rm.{William Robotham - Chief Engineer} show you a
mock-up of a drum with helical ribs. We have now had
this scheme produced in a solid drum and the cooling is
satisfactory but the drum is 3½ lbs. heavier than standard.
So aluminium drums are our first choice.

Any information you can elicit about light
alloy drums will be very welcome.
