| To By.{R.W. Bailey - Chief Engineer} x694 3/2 Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}6/KW.20.10.34. Bifurcated Rivetting. We have discovered that when this type of rivetting is used for clutch driven members in which the fabric is rivetted to the driven member and not to the pressure plates, damage is caused to the fabrics. Will you therefore please instruct the ordinary type of rivetting on clutches that have the fabric on the driven member; that is to say, on the SpectreCodename for Phantom III, 20/25 clutch to N.Sch.3948, and the latest Bentley Clutch to N.Sch.4190.
