Porsche 906 chassis 146, one of only 52 examples built with the 901/20-type Carrera 6 engine, was delivered in April 1966 to Racing Team Holland — a squad backed by the Dutch royal family including Prince Bernhard — and finished in orange with royal blue seats. It enjoyed one of the longest competitive careers of any 906, with victories at Zandvoort and elsewhere under drivers including Wim Loos, David van Lennep, Ben Pon Jr, and Arie Ruska, before passing through several Dutch owners and eventually receiving a documented body-off restoration returning it to its original orange livery.
