| Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} E. {Mr Elliott - Chief Engineer} C - Mx. {John H Maddocks - Chief Proving Officer} X236 BY9/W.25.8.33. Bentley Piston. Referring to Hs {Lord Ernest Hives - Chair} /Rm {William Robotham - Chief Engineer} 6/MA.22.8.33,and E.1/HP.24.8.33, it is evident that some misunderstanding has arisen in connection with the supposed change of dimension on the lands between the rings on the Bentley piston. I have examined all the drawings to find out if and when a change was made,but find that in each case the dimension is the same,namely 3.270-5,the lengths being taper from 3.230 to 3.243. BY. {R.W.
