Turns out my old man got an ibex on the first day of the 2nd trip. He followed a huge male over a ridge with the guide who spotted it again just over the rise. A 270 broke it's neck at 235m and then of course they realised they had shot a smaller male, albeit a decent trophy.
Fortunately, he had two licences and was able to shoot a larger male the next day at 260m, from a large herd that was stalked in the snow.
I'll post pictures asap.
