If you are wanting an apple tree that's 12 to 13 ft tall then I'd start
again and get a tree from a reputable grower this Autumn and take his
advice on which rootstock you should have.
I think you could still be waiting for your present tree to make that
height in 10 years time.

Yes - that had occurred to me. The tree could also be in a slightly
different position, so getting a new tree would seem a sensible option.
I've also heard that orange cox pippins can be disease-prone.

Why did you suggest Autumn for buying a nw tree in particular?
