It is found that if the Bentley Oil Filler Tube EB. 394 is produced in Magnesium, the Coupling Piece E.{Mr Elliott - Chief Engineer} 83227 which is rivetted to it cannot be chromium plated owing to the violent chemical action which takes place between the Magnesium and the plating solution. The Magnesium casting is 5 ozs. lighter than the standard one in Aluminium, so that if this saving in weight is considered worth having, it will be necessary to adopt other means of securing the Coupling in order that this may be plated before assembly.
