| To RHC.{R. H. Coverley - Production Engineer} x206 Hs{Lord Ernest Hives - Chair}/AFM.{Anthony F. Martindale}17/KW.28.2.36. Bentley Rear Aluminium Composite Brake Drums. With reference to the steel liner instructed in Hs{Lord Ernest Hives - Chair}/AFM.{Anthony F. Martindale}12/KW.12.2.36. The reason for asking for this ring to be formed from a flat strip was to keep down experimental costs and to develop a cheap means of making such rings for production. However, it seems that our request for this type of fabrication is likely to delay the four drums described in Hs{Lord Ernest Hives - Chair}/AFM.{Anthony F. Martindale}9/KW.20.2.36, and as we are anxious to avoid this, will you please make this ring from one of the two spare steel drums instructed in Hs{Lord Ernest Hives - Chair}/AFM.{Anthony F. Martindale}1/KW.10.1.36. The chamfer on the inside will not matter. At the same time we would like you to find out by trial if you can make a ring in this manner and so have ordered from Mr. Marriot a strip of 6 gauge 0.3% carbon steel.
