Here is a scan from a book on RAF Helicopters, the first 20 years. RAF aircraft used Grey/Green from the early 1950s up to the 1990s, never Brown/Green.
Confirmation is here...

Sorry that the serial numbers are not readable.

This is my candidate for a re paint 110 sqn RAF in rescue YELLOW from 1959, the serial is XJ426, from a book written by a crewman on 155 and 110 of that time. Forgot I had it in my library!
