| FROM E.{Mr Elliott - Chief Engineer} C. to HS.{Lord Ernest Hives - Chair} ORIGINAL EAC.10. SPORTS PHANTOM. X.8190 OIL GALLERY PIPE. We send herewith drawing LeC. 2484. shewing the above. We are asking for this pipe to be sweated, not brazed, to avoid the accumulation of scale which was said to occur in the RR.F. aero engine gallery pipes with brazing. R.{Sir Henry Royce} says he would like to know how it is these latter pipes were brazed when sweating was specified on the LeC. drawing. E.{Mr Elliott - Chief Engineer} RECEIVED NOV 18 1927 | ||
