Clapham} 3/SW.6.5.40. Bentley V. {VIENNA} Production Front Dampers Please note that as a result of recent investigations we find that it is essential for the replenishing valves to be lapped onto the pistons owing to distortion of the pistons. Combined with this, a groove .100" wide and .015" deep becomes necessary to give the required leak. Please instruct production accordingly. ------------------ Rm {William Robotham - Chief Engineer} /Clm. {D. D. Clapham} | ||
