In our memo E2/M26.11.26., we gave Mr. Royce's criticisms of the scheme submitted for the above.

It occurs to us there is a question of mounting the pinion on the end of the camshaft so as to leave the oil flow unimpeded, and that one way of doing this is as shewn below. We send this to you only as a suggestion, not yet approved by S.
