R.{Sir Henry Royce} recommends that we should introduce the thicker crankshaft flange on production as quickly as possible. The flange in question is the one to which the flywheel is bolted. I confirm my verbal instruction to look into this and let me know the position, when I will decide where we can bring it in. BY.{R.W. Bailey - Chief Engineer} | ||
