Chassis 83807 is a supercharged Mercedes-Benz 770 K Pullman Cabriolet, bodied by Karosserie Voll & Ruhrbeck, ordered in late 1930 by King Faisal I of Iraq as a state vehicle and delivered in August 1931. It subsequently served two further Iraqi monarchs before being overhauled in Stuttgart in the late 1950s. In 1967 it was acquired by the Indianapolis Motor Speedway Museum, where it spent over five decades on display. It retains its numbers-matching engine and original Arabic license plates.

This car's public record is built from its auction and competition history. Register your ownership and privately add your own records to make it a verified Legacy Metrics passport — provenance that backs your car's value at sale and gives your insurer evidence to price against. Roy reviews and verifies every registration personally.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections. The summary is Legacy Metrics’ own writing; we do not reproduce catalogue text.

“Full” and “partial” documentation labels indicate how well each entry is corroborated in the underlying sources, not an audit of the car’s physical paperwork. Names of recent or living owners are withheld for privacy.
