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.
