The polar opposite, this tree is in rather poor health. I'll probably just fell it, I don't think there is anything worth saving here, it's likely as rotten inside as it is outside due to its severe wounds.
That bark-less branch stump there is unfortunately typical of how old folk here pruned their trees. It's really bad. The tree cannot heal this and parasites, fungi and whatnot will attack it until it gets too sick.
This one does bear some sick apples and fungus infected leaves. It's not completely dead but clearly dying.
