1956 Rolls-Royce Silver Cloud I H.J. Mulliner Drophead Coupé (Style 7410)

LSDD146roadUnited Kingdom
Colour
Velvet Green

Chassis LSDD146 is one of only 21 examples of the H.J. Mulliner aluminium drophead coupé on the Rolls-Royce Silver Cloud I, style number 7410, and among the dozen built to left-hand-drive specification. Ordered in 1956 by American resident Dorothy Staniar Assheton with an array of bespoke specifications, it was delivered in London in June 1957. The car passed through just three ownership chains before sale, spending three decades on display at the Auburn Cord Duesenberg Automobile Museum. A later restoration returned it in Velvet Green over biscuit tan leather, while the original engine, woodwork, and identification plates are retained.

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.
