Isaac Newton Apples at last

My Isaac Newton tree, a specially grafted clone of the tree that grew in the garden of Woolsthorpe Rectory in Newton's day, has at last set fruit.

I've had the tree for at least 15 years and it didn't flower at all until two years ago, and then only sparsely, but this year there were lots of flowers, and today I spotted several tiny apples.

Incidentally the variety is Flower of Kent, though I think the only ones grown are the clones of the Woolsthorpe tree.
