Both Sikorsky S-37 aircraft were operated by American International Airways, which was associated with NYRBA, the short-lived New York, Rio & Buenos Aires Line. Reportedly the other one operated in Argentina as R-1283 Southern Star. This airframe became NR942M, a seaplane that undertook a failed flight around the world - see other photos.

The Fleetster was designed for use within South America by NYRBA Line, a forgotten competitor to Pan Am in which Consolidated's Reuben Fleet held an interest. The Fleetster would fly through the night with evening mail to catch up with the diurnal NYRBA flying boat at its night stop. Pan Am's powerful backers deprived NYRBA of a US Post Office contract. NYRBA could not survive and NC657M was returned to the factory. The factory airfield was north of Buffalo. Photo from: Consolidated / Gerald Balzer collection
