Coverley - Production Engineer} re Bentley Flywheel and Crankshaft. Please receive herewith drawing LeC.3549 showing the flywheel modified to use up the 15 crankshafts already made, having 8 bolts. It will be noticed that the flywheel is now joined to a separate flange, which is bolted to the shaft made in 3½% Nickel Steel. The flywheel can still be made from the forgings or even from the seven finished scrapped flywheels if it is considered worth while. Drawing to BY.{R.W. Bailey - Chief Engineer} Blueprint to RHC.{R.
