Chassis BC1LB is one of only six second-series 'B' Bentley R-Type Continental Mulliner fastback sports saloons built with left-hand drive and manual transmission. Delivered new in July 1953, it was returned to the Crewe factory within a year following a serious accident and completely remanufactured: new welded chassis, a 4.9-litre engine, and an entirely fresh Mulliner body, with the factory issuing a second three-year guarantee upon completion. Subsequently upgraded with a six-port cylinder head (the so-called OPWAS modification), the car has accumulated numerous concours honours and a competition record in modern touring events.

Maintenance & restoration

  1. 1954Restoration
    Bentley Motors (Crewe factory) and H.J. Mulliner

    Following what is believed to have been a serious accident, the car was returned to the Crewe factory and entirely remanufactured: the chassis was rebuilt to the latest lightweight welded-frame design, a new 4.9-litre engine was fitted, and a complete new Mulliner body was constructed to the original design. The factory considered it 'as new' and issued a fresh three-year guarantee. Only select trim pieces from the original build were retained. The transmission is also believed to have been converted to the centre-shift configuration at this time.

    Fully documented in original factory build paperwork and recorded in Christian Heubner's Bentley R-Type Continental Register.

  2. 1988
    Restoration

    Full body-off restoration carried out, refinishing the car in Masons Black with a Tan leather interior to its current appearance. Partial photographic documentation of the work is present with the car.

    Restoration was undertaken during Alan W. Rothschild's ownership and preceded the car's concours campaign from 1988 to 1992.

  3. 1997Modification
    Vantage Motorworks

    An air conditioning system replicating the installation fitted to the 1953 New York show car — the sole R-Type Continental known to have received factory air conditioning — was added to the car.

    Work carried out in keeping with the car's history of period-appropriate enhancements.

  4. Modification

    During the tenure of the previous decade-long owner, the engine was upgraded with a big-valve six-port cylinder head (as used on the Bentley S1), larger SU carburettors, a special distributor, and an enlarged tailpipe, raising output to approximately 178 bhp. A correct aluminium radiator sourced from the UK was also fitted. This package, known as the OPWAS modification, was originally offered by the factory as a retrofit from 1955 and is fully reversible, as the removed original components are included with the car.

    Invoices from Vantage Motorworks and Paul Russell & Co. covering maintenance during this ownership period accompany the car.

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.
