Slate grey

A rare 1961 Porsche 356 B 'Twin-Grille' Roadster bodied by D'Ieteren of Belgium, one of only 248 produced as a transitional model between the Drauz-bodied Roadsters and the 356 C Cabriolet. Completed in late 1961 in Slate Grey over green leather and originally distributed through Porsche Car Pacific in San Francisco, the car underwent a thorough three-year bare-metal restoration in the early 2000s, retaining its numbers-matching drivetrain though with a period engine displacement upgrade.

Maintenance & restoration

  1. Restoration
    Automobile Associates

    A comprehensive three-year bare-metal restoration returning the car to its factory-correct Slate Grey over green leather specification; the car was fully stripped and refinished. The numbers-matching engine was retained but bored out from 1,600 cc to 1,750 cc and fitted with an SC camshaft during the process.

    Work was commissioned by James Newton on behalf of a client. The car was reported to be accident-free prior to restoration. Completed circa 2002–2005.

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.
