1927 Delage 15-S-8

Chassis 4 was sold to Chiron after Delage disbanded its racing program due to financial strain. He campaigned it at Indianapolis in 1929.

Senechal raced the car in major European Grands Prix during 1930 and 1931 before selling it at the close of that season.

Howe also owned the sister chassis 3, which he crashed at Monza in 1932, shifting his attention to chassis 4. He used the car extensively in continental Voiturette events through 1935.

Seaman hired former Alfa Romeo test driver Giulio Ramponi to develop the car, focusing on weight reduction and conversion to hydraulic brakes. His success attracted Mercedes-Benz, after which he no longer needed the Delage.

Noted racing team owner who acquired the car from Seaman. Two additional chassis were later referenced as having been commissioned by Prince Chula.

Parnell acquired chassis 2 and 4 along with original spares and additional chassis post-war. He reassembled three complete cars by mixing components, including fitting engine number 3 from the crashed Monza car to chassis 4.

Friend of Parnell who raced the car at two major events in 1946 before selling it on.

Walker cared for the car for over thirty years, supported by mechanic John Chisman. A workshop fire in March 1968 destroyed the original bodywork and firewall, after which Chisman rebuilt the car. Walker's last public outing with it was a 1984 retrospective event.

French collector and publisher who acquired the car following Walker's final appearance with it. Pozzoli died in 1992.

Walker's last recorded public appearance with chassis 4 before transferring it to Pozzoli's collection.

Extensive weight reduction carried out and braking system converted from mechanical to hydraulic operation, supervised by former Alfa Romeo test driver Giulio Ramponi at Richard Seaman's direction.

Ramponi was retained specifically to oversee the car's further development for the 1936 Voiturette season.

Following a serious fire at Rob Walker's garage workshop, the car's original body and firewall were destroyed. Walker's mechanic John Chisman subsequently rebuilt the car.

The fire caused irreversible loss of original bodywork and firewall.

A comprehensive restoration was commissioned from Auto Restorations of Christchurch, New Zealand, described as an exact recreation following the acquisition by a Brazilian collector.

The catalogue text appears to be truncated at the description of this work; full scope is not stated in the available prose.

Post-war reassembly by Reg Parnell involving components mixed across multiple 15-S-8 chassis. Engine number 3, recovered from Earl Howe's Monza crash car, including its crankcase, was installed in chassis 4.

This work resulted in each reassembled car losing some degree of individual identity, though all retained original and period-correct parts.
