Chassis B137LE is a 1939 Bentley 4¼-Litre all-weather tourer bodied by Thrupp & Maberly as a four-door, four-passenger convertible, and one of only one hundred LE-specification cars built. Delivered new in June 1939 to J.T. Johnson, it retains its original body, chassis, and engine, making it a fully documented matching-numbers example.

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.
