Chassis 49304 is a 1938 Delahaye 135 M bodied by Chapron as a cabriolet with distinctive pontoon fenders. Dispatched early that year, it passed through Dutch private ownership before spending 44 years in prominent Dutch museum collections, first at Automuseum Driebergen and then within the Louwman Collection. A 5,000-hour nut-and-bolt restoration was completed in 2005 by French marque specialist Ian Polson, upgrading the car to 135 MS specification with triple carburettors. It was subsequently exhibited at the 2007 Concorso d'Eleganza Villa d'Este.
