Fowler Clarke - Electrical Engineer} 5/T13.7.17. X.3066 - RE STANDARDISATION SHEETS We have not yet had from you a list of Aero Engine parts for standardisation, as the result of sending you copies of our urgency list of experiments. We are now suggesting [handwritten correction: suggest] a few of these in the list below. This list is probably not complete, and may include some that are not for standardisation, but we give it as what we think may be standardised. Will you kindly let us know which of these we may standardise right away, and also suggest any others you may have in mind. X.3015 - 3-Way petrol connection for R.R.C.H. carburetters recommended by Mr. Hives for standardisation. (Eagle(Aero Engine)). X.2843 - New type castellated nuts to LeC.710 incorporating alterations instructed in Mr. Elliott's memo E1/B31517. (Eagle(Aero Engine)). X.2850 - Main bearing bolts with ground stems to LeC.714 incorporating alteration instructed by Mr. Elliott's memo E1/B1617 in the case of the Falcon(Aero Engine) only. (Eagle(Aero Engine) & Falcon(Aero Engine).) X.2909 - Improved and lightened type camshaft drive (Eagle(Aero Engine)). X.2926 - " " " " " " (Falcon(Aero Engine)) X.3001 - New type tappet adjustment to LeC.775 but with spherical instead of cylindrical surface tappets. X.2678 - Oil pump annulus in nickel steel to give a Brinell figure of 220 ( Would you kindly see [handwritten correction: say] if it has been decided by the Works whether they would prefer to use [crossed out] the [handwritten insertion] standard hardened type annulus).
