Since you have info on Stuka I will give you my insights on the mother, Olka.
Father: Arno is out of showlines on the topside and Kata Anrebri on dam side. I am not always super fan of Anrebri dogs but in this case the motherline of Arno through Kata is super. Kata is out of Bob Cega, who was an extraordinary dog and producer. He is out of the B litter Cega, which is one of the great breedings of alltime. Six dogs in this litter were Sch three and good hips and three of these dog were national competitors. Bob's sire is Grisha Schwarzen Milan, a dog with fair hips but tremendous producer of working ability. When bred to Gita Salrak, they produced the B litter Cega. (BTW, Gita is very prominent in pedigree of Andy Maly Vah). On Kata's damside we have Gaston z Blatenskeho zamku as sire who was a very strong dog, who was out of Chasan, a national competitor and Klara, a very controversial dog in that she was mild in hips, but threw FABULOUS temperament.
Olka's motherline is very nice also. Dara is out of Jax. Jax is a son of Arys z Travnickova dvora, who was super super dog. Arys's mother Cita z Vrtovske, is sister to the great Cir z Vrtovske, who was one of the great great dogs in the Czech Republic.Jax's mother, Fency Gymor, was a very solid female out of the great producing female Alice Gymor. Alice was also mother of the great Dark Gymor. (years ago I hd a son out of a Dark Gymor daughter).
Dara's mother line goes to Brema who is old Czech bloodlines.
All in all, Olka has some super blood in her pedigree and mixing that with Stuka and you have nice genetic base. Of course there are other elements to this pedigree, but I think you have the gist, and more detail I'm not sure is beneficial.
