Sikorsky R-4 First helicopter to enter RAF service!

Your photo may very well be a photo of the first Hoverfly 1(Sikorsky R-4) to enter service. But the book I obtained my info from. ‘ RAF HELICOPTERS The First Twenty years’ by Wing Commander Dowling. Published by HMSO 1992. States that the Hoverfly 1 first was in service in 1944. The first helicopter pilot training course was held at RAF Andover in 1945 using the Hoverfly 2.
