At the Conference with Sg.{Arthur F. Sidgreaves - MD} on 20.1.37. it was asked what would be a convenient height to which to increase the ribs on Bentley rear drums. We say that the outside diameter of the ribs should be increased from 13.375 to 14.000". Will you please prepare a new drawing to these dimensions, and we will then fit same to a car.
