Colour
Pacific Blue over red leather interior

The Aston Martin DB Mark III Drophead Coupé, chassis first delivered in March 1958 in Pacific Blue over red Connolly leather, is a rare and historically significant example among the 551 cars built between 1957 and 1959. It was originally supplied to David Brown — the industrialist who owned Aston Martin and gave the DB lineage its name — and principally used by Lady Brown. After decades in storage it was professionally restored by Aston Martin Works and retains its original colour scheme and registration number 110 RMD.

Maintenance & restoration

  1. 2010Restoration
    Aston Martin Works

    Following its reappearance after roughly three decades in storage on a trailer under a tarpaulin, the car was fully restored by Aston Martin Works.

    The car had not been driven during its long storage period and was described as a rolling restoration project when it came to light in 2010.

  2. Modification

    A dual exhaust system was retrofitted to the car after original delivery, raising output by approximately 18 bhp over the standard single-exhaust configuration.

    The car was originally delivered with twin SU carburettors and a single exhaust; the upgraded system was added at an unspecified later date.

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.
