Introduced in 1928, Riley’s six-cylinder engine famously went on to underpin ERA’s racing powerplants. The ultimate road-going version, the 15/6, became available during 1935 and could be had with a range of open and closed coachwork. A popular addition, the Adelphi Six-Light Saloon body was a far more commodious and practical proposition than its Kestrel sibling. Trimmed to a better standard than the equivalent four-cylinder model, the Adelphi 15/6 was a strong performer with a reputed 85mph top speed. Although, survivors from the estimated production run of 230 cars are a rare sight today.
First registered as ‘RV 9051’ in Portsmouth on 4th June 1936, chassis 46A2751 appears to have survived the last eighty-six years remarkably well. Thought to pleasingly retain much of its original Green leather upholstery, the Riley is understood to have been treated to a thorough engine overhaul by Ian Gladstone of marque specialist Blue Diamond Services during the early 1990s. Frequently rallied by then keeper Anthony Duff Esq. including various continental excursions, the Adelphi is said to have been entrusted to Brian Lloyd-Jacob in the early 2000s to have its straight-six checked over and uprated with high compression pistons. Entering the current ownership during 2004, the 15/6 has been enjoyed on the Beamish and Eskdale rallies as well as for trips to Prescott, etc. Treated to a new rear window seal, overhauled distributor, and general servicing by the seller, he has also installed an SU carburettor in place of the original Zenith. Laid up alongside its Kestrel stablemate in recent years, the Adelphi is currently running and driving but would benefit from recommissioning prior to sustained road use. Very much an ‘oily rag’ car, this rare surviving, six-cylinder Riley is offered for sale with a V5C Registration Document, reprinted instruction book, sundry invoices, and various old MOTs & tax discs dating back to 1990.
The car is running, it has a unique 6 cylinder 1726 cc with high compression pistons, SU carburettors, preselective gearbox and offers a good basis for conversion to TT Sprite racing.
