The Sikorsky S-43 first flew in 1935 and was often called the "Baby Clipper" after it's larger Pan Am big sisters, including the Sikorsky S-42. Various seating arrangements were available accommodating between 18 and 25 passengers, with a separate two-crew cockpit forward. JRS-1 was the US Navy and US Marine Corp's heavily militarized version.
"53 S-43/JRS-1 "Baby Clippers" were produced (31 civil, 15 Navy, 2 Marine, and 5 USAAC)...... 10 of the Navy's JRS-1s were at Pearl Harbor on December 7th, all survived the attack and one, BuNo 1063, is undergoing restoration at the Smithsonian today. Two civil S-43s have also survived, one originally owned by Howard Hughes and one at the Pima Air and Space Museum (painted as a Marine JRS-1)."
