It is reported by the Experimental Department that there have been several cases of the front brake toggles collapsing due to increased braking. This is the stiffened toggle GB.2434. We send herewith N.Sch.5129 showing a further stiffened toggle which will apply to the present Bentley, and also Wraith IIX. The increased bending stiffness is in the ratio of 9 to 20, and this is an indication of an increase in the strut strength. This should replace toggle GW.699. Att:N.Sch.5129.
