Dunstable – Sunday 4th June 2017 (John Tomlinson)

After Luton it was to be a relaxing ‘pit stop’ to view the glider activity at Dunstable~Beds.
It was my first visit here and very interesting, having a sandwich and drink, watching the movements below.
I understand that the airfield is not always accommodating with visitors. However I was able to take a few reasonable photographs.
The request:
Does anyone know what this glider is. It looks ‘distinctive with it’s colouring’? :  https://www.flickr.com/photos/jlt_egcc74/34987521531/in/album-72157681759073132/
