The 'Mexico-Excelsior' Ryan Brougham Type B-1 Monoplane was built by the B. F. Mahoney Aircraft Corporation in San Diego, California. Seen in this picture taken in San Diego at the time of delivery in late May 1928, the aircraft had a wing-span of 46', a length overall of 27' 9" and a height overall of 9' 10". The fuselage was constructed of welded steel tubing and the wings were of wood with fabric covering similar to that used on the fuselage. The aircraft was fitted with special long-range gasoline tanks for a total of up to 430 gallons of fuel. Power was supplied by a 225 hp Wright whirlwind engine built by the Wright Aeronautical Corporation in Patterson, New Jersey.

When not loaded with fuel for long distance flights, the Exceslior had a cruising speed of 105 mph, a maximum speed of 125 mph, a landing speed of 49 mph, a climb rate at sea level of 900 - 1,200 ft / min, and a service ceiling of 16,000 feet. It was equipped with altimeter, tachometer, airspeed indicator, oil pressure gauge, oil temperature gauge, altitude adjustments, magnetic compass, turn and bank indicator, and dashlight. In addition, the aircraft was equipped with a pioneer earth inductor compass for transoceanic navigation.

The aircraft was a light silver color with the words "Mexico-Excelsior" painted on the fuselage. It was later designated as M-SCOM and was marked with the Mexican Army Air Corps emblem.
