I got it from Rise of the Flight team member. I also check these data in Profili program ( unfortunately it shown only Clmax for 13 deg Aoa) and by these site:

worldofkrauss.com/foils/search

Airfoils names:

- Pflaz DIIIa - Geottingen 79 ( Pflaz 11)
- Albatros DVa - Geottingen 173 ( ALbatros 6020)
- Fokker DVII - Geottingen 367

You could check it on the site which i wrote above. Just serach profile by name then click on it - You will get polars. ( but only for small Reynolds number)

I was also suprised that such airfoils like Pflaz and Albatros had have such high Clmax.
