This is one that Donald Compton using a pollinator-seedling he named ‘Thor’ x ‘Rosseyanka’. It’s the only photo I have.
It is monoecious, having male and female flowers on the same tree; many-male flowers as shown when groups of peduncles in more than one gather from a single location.
It’s listed in England’s Orchard and Nursery Decemember 2022 Trees & Shrubs Catalogue
