Looks like he could have been photographed at the family home while on leave.

Certainly not looking like that in Review Order, that particular photo would, almost certainly, have been taken at either Whitehall, Knightsbridge or perhaps St Johns Wood (the latter is most unlikely) in London or Combermere in Windsor.

This was George's home

Is it still in the family or did they sell up?

Unfortunately not - I'm not sure of the date of this photo ("STANTON, A Rural Village Past and Present", Stanton Parish Council 2002), but Smithymoor Farm has now been gentrified - I've only been inside once and that was years ago.
George Smith Senior died in 1903, aged only 60, and I think Granny Smith moved out some time after that - but she continued to live at Stanton until her death. it's all a bit vague I'm afraid.
Apparently George Smith Senior was so tall and heavy that they had to rest the coffin a couple of times on the way to the Church from the Farm - another myth? (But there's usually an element of truth, isn't there?).
The personal details you attached - they don't belong to George, do they?
Someone queried where he was buried; we know it was Windsor, but perhaps he would have been buried in an ordinary (not military) churchyard?

Okay, well I suppose that is the way things are in England and has been for quite a few decades now, farming is a tough world to be in, you have to get it right or go under.
The family "story" is, I dare say, probably very true.
Yes, the details are indeed his, six feet tall, as you would expect, I would have a chat with the archivist at Combermere if I were you and perhaps a visit to Holy Trinity church in Windsor would be in order.
