Front Suspension - Myth.
PL.505, attached to Rm{William Robotham - Chief Engineer}/HH's copy of this memo, shows modifications necessary to the upper and lower triangle levers of the Myth front suspension in order to obtain endwise compression on the Harris bushes used in these levers. This scheme will therefore modify PL.423 and PL.426, and in addition, the male member of the upper bearing shown on PL.378 is altered.
The dimensions shown on PL.505 have been approved by Howard Graham Ltd., the suppliers of the Harris bushes, and are in accordance with their drawing, No.040.
