To be fair, for a 50 year old bike, that has never been repainted, I think the £795 Galaxy does look very well cared for.
As for the handlebar position, very occasionally I have seen people riding with handlebars in that position when the reach is too great (riding a frame that is much too large). In this case the bike has reportedly had one owner who is now elderly, so the issue might be that they developed back problems that stopped them reaching the bars in their proper position. It seems unlikely that they bought the bike new and rode for 50 years with a reach that was too great. But hey, maybe it was on sale all those years ago, and they convinced themselves that despite being far too large, the frame size didn't matter.
Anyway, I suspect that the £795 Galaxy listing is how the seller of the £900 Super Galaxy got the idea that they could get an extra £105 for having the Super version of the Galaxy. And despite the fact that the £900 Super looks very unloved compared to the plain Galaxy.
