I'm also looking for this cultivar. I don't think I can find it in Europe.
I could barter it for some good french cultivars, but only next year. This year I have already cut all the scion wood I can cut off my young trees.
Some interesting cultivars I have :
Apple
"Patte de Loup": original looking apple with a great taste.
Apple "Karneval": recent cultivar with great colors. I haven't tasted it yet.
