This aircraft is a Ryan B-1 Brougham, S/N 49. It derives from the same lineage as the “Spirit of St. Louis”, and was built during the same year. The B.F. Mahoney Aircraft Co., San Diego, CA manufactured it on 1 November 12, 1927, It was equipped with a 200 HP Wright J-5CA engine, S/N 2092, built on October 17, /1927. It weighed 3,300 pounds.

Southwest Ryan Airlines, Inc., 1204 Atlas Bldg., Tulsa, OK (Al Henley, Mgr.) purchased it on November 12, 1927. This Ryan passed through the Davis-Monthan Airfield twice. Each flight was eastbound from San Diego to Tulsa, and each flight coincided with major airframe modifications performed at the Ryan factory in San Diego.

The airplane was modified at the factory, “with larger wing and fuel tanks to endeavor to establish world’s endurance record.” In a letter from B.F. Mahoney on January 9, 1928, he states the “regular wing removed and larger wing put on (42’ span to 46’ span), with larger tanks in fuselage to replace 3 passengers as 2PCLM (Al Henley & relief pilot) brakes and all unnecessary equipment removed. Flight only over airport at Tulsa. Gross wt. 5,440. Remodeled 1/7 to 1/19 1928.” An “X” license was applied for on January 9, 1928, and approved by wire on January 10, 1928.

Below, an image of the airplane under construction from Ryan Aeronautical. NX3598 was very similar to Martin Jensen's MGM Brougham. They had the same longer span wing and fuel tanks in the belly.

The first visit to the Davis-Monthan Airfield occurred on January 13, 1928 at 2:45 PM. The pilot was Al Henley. He departed for Tulsa the same afternoon at 3:30 PM. The date of this visit is earlier than the date given in Mahoney’s letter for completion of the remodeling work. But, chances are the work was completed earlier, and the transient log date entered by Henley is accurate. Please click to see images of pilot Henley and this airplane on this site with its NX registration.

On February 6, 1928 the airplane had an accident at Fort Worth. The pilot was Al Henley (transport license #778) carrying passenger Joe Hart. Both were uninjured. A wheel collapsed on take-off because of the excess load. It is not clear if the endurance record was being attempted when this accident occurred. The airplane was sent by truck to the factory in San Diego for rebuilding. It was rebuilt as of August 10, 1928 to the regular Ryan B-1 specifications for ATC 25. The 42 wing was replaced. A Wright 220 HP engine, S/N 8157 was installed.

Below is an image of NX3598 During the time of the west coast to Tulsa flight. The image is from the SDAM Flickr stream, and the caption o that site reads, "Pot Bellied Brougham 'pregnant guppy' ordered for a trans-Atlantic flight to Rome not paid for, was flown over Oklahoma in an attempt to set an endurance record."

It appears that the record attempt was scrapped. A “NC” license was issued for the airplane on January 11, 1929.

On March 1, 1929 it was sold to the Garland Aircraft Corp., Tulsa, OK, and then on March 6, 1929 to John Fernow, 1123 North Denver St., Tulsa, OK. It was flown for several months and then sold again to Earl Bunker Smith, 6122 East Olive St., Pipestone, MN who installed a new, larger tail unit (installed by von Hoffman Aircraft Co., St. Louis, MO).

It was purchased on May 27, 1930 by L.H. Atkinson, Municipal Airport, Tulsa, OK for use with Oklahoma Short Line Airways. On June 23, 1930 the Commercial Credit Co., Oklahoma City, began repossession procedures for non-payment of mortgage. And on August 9, 1930 a violation was cited for operating on a passenger airline without seat belts for pilot or passengers. Kenneth M. Oliver (not a Register pilot) was the pilot-in-command at the time, but he received a warning only.

It was sold for $1,000.00 on May 29,  1931 to Sam H. Coffman, Airport, North May Ave., Oklahoma City, OK. No further information.
