| ORIGINAL FROM R.{Sir Henry Royce} SECRET. R4/M23.3.25. Copy to - [REDACTED] [REDACTED] [REDACTED] H.S. E.{Mr Elliott - Chief Engineer} A.{Mr Adams} C. CYLINDER HEAD. (Handwritten: X 8050) This requires further comments. Regarding copper tubes through cylinder castings, these I understand to be more reliable than steel, monel metal, or brass. I assume that difference of expansion is taken up within the elastic limit considering the bolts put the whole in compression. R.{Sir Henry Royce} | ||
