| 1044 To HPS.{Horace Percy Smith - Experimental Factory Mgr} Rm{William Robotham - Chief Engineer}/Std.5/JH.23.9.38. Attached is a memo. from H1/EA. re B.60 cylinder heads which have been sent to him for anodic oxidation anti corrosion treatment. This treatment is considered to be particularly necessary on B.60 engine and for it to be of any use, the head to be oxidised must be free of burnt oil coatings etc. Will you please take steps to see that future heads both B.60 and B.80 are scrupulously clean in this respect.
