Thanks harmony. Insightful advice as usual
The distance is a nuisance and no mistake. But in looking at lots of options it is very clear to me that Fells make my heart flip like no other equines do, so given how much work they are, I think I would be wise to take my own advice (originally from BH) and "Buy something you like the look of, because you are going to have to go out in all weathers to look after it, so it really helps if you like what you see when you get there"! And at present, most of the mature, ridable Fells (that I can afford) available are in the north of England - perhaps not surprisingly, as that's their home ground.
I will certainly ask the owner many more questions before making any commitment in terms of travel to see him, let alone transport him. She did some events with him in his younger days, so he is - or was - used to being loaded, and I would expect her to do a bit of refreshing on this score before we expect him to be moved.
And yes, good idea to ask how he is if they meet other horses out on rides, and would there be any horses nearby he could have a meet up - across a fence at first - with to see how he behaves.
I have no idea what to expect really, when he's been in one home and one situation for so long. It will be a massive upheaval for him, and no-one and nothing familiar at the new place. I am aware of the irony that I will basically be doing to this pony what I couldn't contemplate doing to Flossie, who is only a very few years older... But that is the owner's choice, she would rather have him in a home where he is used while he still has active years in front of him, and then retirement in the same home.
But he will be coming to a home where he will get kind and considerate handling from experienced people who will genuinely care about his emotional wellbeing as well as the physical, so I hope he will find that, plus Flossie as a fieldmate, a good situation to be in, once he's adapted to the change.
