For those of you who are interested i can send seeds of this tree. i just collected fruit of a large fruited variety, that makes yellow somewhat pear-shaped fruit.

unfortunately all my seeds are gone for this year, but i will surely have seeds next year again.
I have, however , received sorbus domestica seeds for free from the american GRIN seedbank before that germinated very well so i would suggest you should try and contact them for the time might be right just now.
If not i might have seeds again next year (sorry)
