In his 1983 edition of “Grand Prix Bugatti” the car’s owner was (incorrectly ?) given as Rouhaud, Paris (France). It was still supercharged. In the British Bugatti Register published in 1974 the owner was shown as M. Nicolosi of Avallon, France. In Summer 1996 the car was noted in the ownership of John Kendal in Boston, Massachusetts. In 2004 the car was still in the USA. Recent photographs of the car show it painted pale blue, fitted with alloy wheels and headlamps and in immaculate condition.
