Saw a Grasshopper flying at our club back in january - if that was what we were shown when our ab initio group was taken to the hangers to see the gliders I suspect I might have walked out there and then!
Anyway, I took some photos:

We also have a T53 with roundels which flies regularly. Are photos of that required? I could oblige!
Finally yes, Centrair did 'borrow' some ASW19/ASW20 bits from Schleicher to make the Pegase, though the wings are completely different (much more flexible for one thing) than the originals. In my highly biased view (I own one) the Pegase is a delightful glider to fly, and comfortable in the rough before getting into wave proper. Thankfully my Pegase has a grey cockpit interior rather than the nasty pinky-beige that the other one at the club has.
