This is the catalogue record of the Mother Gun, one of 62 models Bentley has placed in the historical record and one of more than seventeen thousand cars the MotorJury library tracks. The record places its introduction in 1927. The photography on this page is hotlinked from Wikimedia Commons under an open licence, with the photographer credited on every frame.
To read the Mother Gun properly it helps to place it in its decade. The 1920s were the vintage era, when coachbuilt bodies, six- and eight-cylinder engines and the first true luxury marques defined a golden age of craftsmanship. Any car launched into that world was shaped by it — by what materials, engineering and regulation allowed, and by what buyers of the day demanded. Its direct contemporaries in this catalogue, introduced within three years of it, include the Adler Adler Standard 6, the British Motor Corporation MG 14/40, the Rover Rover 10 P2 — the cars a buyer of the period would actually have cross-shopped.
The open record carries no verified specification sheet for the Mother Gun yet — no engine entry, no quoted output, no kerb weight. That is not unusual: of the seventeen-thousand-plus cars in this library, thousands are concepts, racers and regional models whose numbers were never formally published. MotorJury's nightly harvest re-reads Wikidata and the Wikipedia infoboxes on every build, so the moment a specification is added to the public record it appears here without anyone touching this page.
Within Bentley's own catalogue the Mother Gun sits alongside the Bentley 3 Litre, the Bentley 3.5 Litre, the Bentley 4 Litre, the Bentley 4¼ Litre.
This library is generated, verified and rebuilt from the open record on every deploy. The catalogue skeleton comes from Wikidata, specifications from Wikipedia's infoboxes under CC BY-SA, photography from Wikimedia Commons under each file's own licence, and the ownership data from United States federal safety records. Nothing is written by hand and nothing is invented: every fact on this page traces to a public source, and every page is rebuilt nightly as those sources improve. Errors in the source record will appear here too — and disappear the night the source is corrected.
Most car databases stop at series production. This one deliberately does not, because concept cars, racing specials and cancelled prototypes are where the industry thinks out loud — the ideas tested in public years before they reach a showroom. Holding them beside the production cars they inspired makes the lineage legible: nearly every landmark road car in this library has a concept ancestor somewhere in the catalogue, and the connections run through the era links on every page.
Some pages in this library brim with specifications; others, like corners of every archive, are thin. The honest response to a thin record is to say so, not to pad it. What is shown here is exactly what the public record supports today — and because the harvest re-runs nightly, the page you are reading is the fullest version of this car's open record that existed the last time the site was built.
The catalogue records what the Mother Gun was; the ownership database records what it is like to own. MotorJury computes a verdict for every model year the United States federal record covers — complaints, recalls, real economy — refreshed nightly, with no opinions involved. If this car reached the American market, its verdicts are in there.
