Not necessarily news, but there is no
Bristol Sycamore for the British available
https://en.wikipedia.org/wiki/Bristol_Sycamore
I've just read in "War Machine", that in Cyprus:
The Sycamore played a crucial role in Britain's operations against the EOKA terrorists, pioneering new mountain flying and helicopter assault techniques and specializing in swift cordon and search operations (sometimes using cabin mounted machine-guns for defence suppresion).
It could carry 2+3, and was used since 1955 in action (available from 1953, though rather in SAR missions), until 1971. If you'd like to add it, a wheeled slender icon like 1908 (Mi-1) would be OK as a quick measure.
An easy addition would be also
Westland Dragonfly https://en.wikipedia.org/wiki/Westland_WS-51_Dragonfly - copied eg. from Canadian 402 Sikorsky S51 (albeit the icon doesn't remind this helicoper and again 1908 would be almost perfect). However, I don't know if they were used for anything else than casualty evacuation. Crew was 1, but it could take 3 passengers.
BTW: I don't know if and when original 524
Bell Scout entered British service, but when it was built by Westland (reportedly from 1965 only?), it was known as Westland Sioux - so maybe it should be renamed Sioux
https://en.wikipedia.org/wiki/Bell_H-13_Sioux Carry capacity was only 1+2, with no place for 3 passengers, and probably no possibility of carrying a cargo.
