1953 Arnolt-Bristol Bolide Roadster (Prototype, chassis 404/X/3000)
- Engine
- 2.0L inline-six, BMW-derived hemi-head, triple carburetors, ~130 hp, four-speed gearbox
- Colour
- Red with tan top

Chassis 404/X/3000 is the first Arnolt-Bristol ever constructed, noted as the prototype in Stanley Arnolt's personal records and carrying the lowest known chassis number. Built on a Bristol 404 platform with Franco Scaglione–styled Bertone coachwork and a Bristol-built BMW-derived straight-six, it arrived in the United States in early 1954 and passed through several owners before entering long-term storage in Illinois. A near-20-year, six-figure restoration returned it to original specification, including a correct period Bristol engine and drivetrain components sourced from new-old-stock parts.

Maintenance & restoration
- 1953ModificationBertone
The prototype was fitted with its Bertone bodywork and subsequently returned to Bristol in England for additional fitting-out and testing. Its original FNS-specification Bristol engine was replaced with a BS1 MK II-type unit prior to export.
Engine swap to production-spec BS1 MK II type occurred before shipment to the United States.
- —Modification
Walter Tormohlen replaced the original Bristol drivetrain with a fuel-injected Chevrolet V-8 engine and a four-speed Chevrolet gearbox, and had the car repainted white with dark racing stripes.
Carried out during Tormohlen's ownership between 1957 and 1965.
- —Bodywork
Robert Schifrin had the car painted blue and modified the grille area, repositioning the headlights and fitting small bumperettes.
Work carried out during Schifrin's three-year ownership beginning in 1965.
- —Restoration
A comprehensive, near-20-year restoration costing over $220,000 returned the car to its original as-delivered configuration. The steel Bertone bodywork was stripped and repaired, then finished in red with a tan hood and interior approximating the original Pine Beige trim. Bristol engine number 100D 754 was located and installed; a correct four-speed gearbox and rear axle were sourced from chassis 404/X/3132, which had been damaged in a warehouse fire and whose components were effectively unused. The valve cover was tagged with the number 212 to reflect the originally fitted engine.
Restoration commenced in the mid-1990s. Correct period-specification mechanical and detail components were reinstated, including Lockheed brakes with Alfin drums and hand-fabricated trunk hardware.
- —Mechanical
The owner who acquired the car in the mid-2010s carried out additional mechanical and cosmetic improvements to build on the existing restoration.
Specific scope of work not detailed in the catalogue.
