Sikorsky H-19

(Source Harold A Skaarup Web Page)
RCN Sikorsky HO4S-3 helicopter, RCN (Serial No. 55320), HS 50 Anti-Submarine Squadron off the coast of Florida, 5 April 1957.
The Sikorsky H-19 Chickasaw (company model number S-55) was a multi-purpose helicopter used by the United States Army and United States Air Force. It was also license-built by Westland Aircraft as the Westland Whirlwind in the United Kingdom. United States Navy and United States Coast Guard models were designated HO4S, while those of the U.S. Marine Corps were designated HRS. In 1962, the U.S. Navy, U.S. Coast Guard and U.S. Marine Corps versions were all redesignated as H-19s like their U.S. Army and U.S. Air Force counterparts.
The H-19 and HO4S-3 were multi-purpose utility helicopters flown by the RCAF and RCN. The HO4S-2 was an air-sea rescue version powered by a R-1340 P&W engine, derated to 550 hp (410 kW). Three were built for the RCN, and two surviving helicopters were subsequently converted to HO4S-3 standard, powered by a 700 hp (522 kW) Wright R-1300-3 engine. Harold Skaarup web page and Wikipedia
