Chassis B23CD is a 1948 Bentley Mark VI originally delivered as a standard Sports Saloon to its first owner in Cardiff. In 2017 the bare chassis was comprehensively transformed by Racing Green Engineering into a B Special 3/8-Litre Racer, an evocation of the pre-war Brooklands and Crystal Palace specials, powered by a Rolls-Royce B-series eight-cylinder engine fed by four SU carburettors and clothed in a tapered open body finished in British Racing Green.

Maintenance & restoration
- 2017RestorationRacing Green Engineering
The Mark VI chassis was fully rebuilt and re-bodied by Racing Green Engineering to B Special 3/8-Litre Racer specification, with a new tapered open body, exposed exhaust, aero fairing, cognac leather cockpit, and machine-turned instrument panel. A Rolls-Royce B-series eight-cylinder engine with four SU Type H.6 carburettors was fitted, along with uprated springs, 19-inch tyres, and a mixed hydraulic/mechanical drum-brake arrangement.
The build concept drew on the pre-war motorsport specials associated with Brooklands and Crystal Palace circuits.
