Yet I have not seen a source what airfoil was actually used on the
Pegase...


For me it is clear, it is an original design obtained following the numerical
work they have done for the airbus wings. So you will not find reference to
a catalogued model.

In principle a flapped glider should be better at both ends, very low speed
and very high speed. The people who designed the Pegase wing could not do
miracles.

I was speaking about an unmodified ASW-20 wing (airfoil Wortmann FX
62-K131) without flaps (or rather: with the flap lever fixed in
neutral position. According to Ferriere Schleicher named this glider
"ASW-24 prototype".


I suppose that if it was a well known airfoil as the one you cite, they would
not take credit of it. Probably also the performance is better than this
classic airfoil, or they would have nothing to be proud of. Now the
performance of our Polish friends show that it is possible to do much much
better, more than twenty years later, with computers infinitely more
powerful, using very rigid materials which allow very thin wings, etc.
