- Offered from the estate of the late Sir Colin Hope who was a former President of the SMMT (1991-93), Trustee of the National Motor Museum (1991-2002), and Patron of the Armstrong Siddeley Heritage Trust from 2011

Introduced in October 1927, the six-cylinder Armstrong Siddeley 15hp could be had with the same range of coachwork as the marque's established four-cylinder 14hp model. Boasting a slightly larger engine (1900cc vs 1852cc) albeit with side rather than overhead valves, the newcomer supplanted its older sibling for the 1930 season.

Entering the late Sir Colin Hope's collection in 1998, this particular Open Tourer example had been supplied new to a New Zealand-based chicken famer some seventy years earlier. The subject of much past restoration work, more recent fettling has including the fitment of a new water pump and replacement flywheel. Little used over the past seven years, it was in running order when photographed during late October 2016 but will require recommissioning prior to road use. The Tourer appears to be complete. The paintwork and interior trim look to be in good order.
