The apricots in the picture look very much like the Anya variety of Candycot. You can purchase two varieties of Candycots from Andy’s Orchard and they will ship them to you (I have done this, and they were excellent).
Anya is one of the varieties.
Most relevant to this post, is the fact that members of this forum have grown Candycot seedlings. You may find this this post especially interesting:

While it is true that seedlings are not exact copies of the parent tree, they can be surprisingly close. Especially in the case of the Anya seedlings.
I purchased some Tatiana scions from @Stan and I can’t tell them apart from the Anya apricots I got from Andy’s Orchard - except that I can pick them at peak ripeness from my tree - so they are much better in that regard.
I also have two Anya seedlings that I planted before @Stan announced that he was selling scions.
Anyway, tree ripened apricots pushing 30 brix are a real treat!
Here is a post on this year’s fruit set on my Tatiana grafts:
