Introduced in 1926, Percy Riley's 9hp twin-camshaft four-cylinder engine was an outstanding design by any standards - various versions powering Rileys until 1957 - so it was not so surprising that to create its first six the firm simply scaled it up, adding two cylinders. This new power unit retained the 9hp four's 60.3mm x 95.2mm bore and stroke dimensions for a total capacity of 1,633cc, and first appeared late in 1928 powering the Stelvio fabric-bodied saloon. Alternative styles on the Six chassis were the Deauville Saloon and Special Tourer, both bodied by Riley's Coventry neighbours, Hancock & Warman. The Coventry marque's pre-war offerings were among the world's finest small-capacity sporting cars and its new 14/50hp Six was no exception. The Six chassis was similar to that of the contemporary Nine, consisting of open, channel-section main members swept up over the rear axle, and measured 10' in the wheelbase. The 'silent third' four-speed gearbox was another Nine carry-over, as was the torque tube form of transmission to the rear axle; the cable-and-rod operated, fully compensating brakes though, were new. For the 1930 season there was an additional Light Six chassis, shorter in the wheelbase at 9' 6" and of narrower track, on which were erected the three Alpine models: fabric saloon, half-panelled saloon and four-seat tourer. Only the Alpine 6/14 saloon survived beyond 1932. This early Riley Six has been in the vendor's family's possession for the last 12 years, having been purchased in the 1990s from marque specialist Barry Gillies, who had restored it. It is believed that the car was exported new to the USA before going to Holland and thence back to the UK. Restoration work carried out by Barry Gillies included an engine rebuild, repairs to the body's ash framework, a new fabric covering for the body, and an interior re-trim in leather. Last in action at the 2011 Goodwood Revival, 'SV 4595' still presents and drives well, and is described by the vendor as in generally very good condition. This rare, Vintage-era six-cylinder Riley is offered with sundry restoration invoices, current MoT/tax and Swansea V5 document.
