This is a Keystone K-78 Patrician trimotor airliner - X-7962 - one of three prototypes - described as a Super-Air Liner - built back in the 1920s. It was a reasonably capable ship for its day - semi-speedy with a capacity of 20-24 passengers. To prove this, one of the Patricians set a payload record on 16 March 1929, flying out of Rogers Airfield, Los Angeles, lifting some 4,600 pounds to 10,200 feet. Piloted by Captain St Clair Streett, time to climb was 25 minutes. The payload consisted of two pilots, a mechanic and 33 girls. Despite this, the Patrician never went into production.
