McLaren is honoring this weekend at Imola one of its most loyal employees, the venerable Neil Trundle, former chief mechanic to - among others - Ayrton Senna and Alain Prost.
Trundle's epic 33-year stint with McLaren began when his former Brabham colleague and Rondel Racing partner Ron Dennis ushered in a new era for the Woking-based outfit.
From McLaren's first MP4 carbon fibre chassis to the team's 'Golden Child', the dominant McLaren MP4/4, Trundle's unwavering dedication accompanied the team's triumphs.
Eventually, Trundle transitioned to the less frantic atmosphere of McLaren Heritage, wrenching on Woking's outstanding collection of revered machines and overseeing in recent years the development of the capable team that will now look after McLaren's historic cars.
This weekend, Carlos Sainz and Lando Norris' MCL35 machines will carry a special message for Neil ahead of his well-deserved retirement.
