Sedbergh, I think that's the one I saw at a vintage glider fly-in at Tibenham a few years ago - as we were helping out with the launching etc we were offered flights in some of the gliders, surprisingly, no takers for the G2! (I went up in a Sedbergh, much more fun than a modern plastic bullet - I think it managed all of 50 knots going straight down!)
Also, there's a Grasshoppper in 611VGS's Hangar too, though I don't know who it belongs to, or indeed if it's airworthy.
