Westland produced a variety of Sikorsky models under licence.
<a href="http://avia.russian.ee/vertigo/west_dragon-r.html" target="_blank">Dragonfly and Widgeon</a> - (S-51). .<a href="http://avia.russian.ee/vertigo/west_whirlwind-r.html" target="_blank">Whirlwind</a> - S-55 (Piston and Turbine versions). .<a href="http://avia.russian.ee/vertigo/west_wessex-r.html" target="_blank">Wessex</a> - S58. .<a href="http://avia.russian.ee/vertigo/west_king-r.html" target="_blank">Sea-King/Commando</a> - S61A/B (SH-3). .(The <a href="http://avia.russian.ee/vertigo/west_westminster-r.html" target="_blank">Westland Westminster</a> which was never production manufactured, utilized the H-37 rotor system).
Westland incorporated British engines into these designs (some, licence manufactured US engines) and generally a variety of modifications that in some cases made the aircraft quite significantly different than the machines they were derived from.
Westland came up with some very good modifications to the original aircraft, some of which were incorporated back into the Sikorsky products. Of these, the commercial Wessex 60 was a tremendous aircraft, as others have explained here. Operating side by side with the S58T's, there was really no comparison between the two!
Can't say I miss any of the British part-numbers and hardware though!
