My Dad was of the RAF guys pushing the helicopter around.

Unfortunately he doesn’t remember the registration of the aircraft, but does remember that it was the Whirlwind and that it wore the RAF SAR colours.

Since this post I have learnt that if it was the Whirlwind that was stored at RAF Finningley it could one of two

XJ729 or XP404
I found a post on these boards relating to XJ729 and that it is in Northern Ireland under a new registration of G-BVGE being looked after and still wearing the RAF SAS colours

If it was XP404 then sadly it looks like she is at Weston-super-mare in a bad way. http://www.ukserials.com/images/ukimages/xp404.jpg
