| AIR MAIL. 1245' W/P. Sr. from Rm.{William Robotham - Chief Engineer} Rm{William Robotham - Chief Engineer}5/R.21.12.37. We have standardised Thermoid on Borg & Beck plate, and, therefore, cannot agree to fit Long plate to your Trials' car at present. We recommend you try a second Thermoid lined standard clutch plate.
