Shotgunlover, you've strayed into the "apples and oranges" realm with your last post. Usually, when we think of the classic British guns, we're thinking of game guns. Sub-7#, works of art in terms of both metal and wood. They were not built to be target guns. But the Brits have built pigeon guns and wildfowl guns, both of which are heavier, more rugged, etc. If you were to ask Purdey or H&H to build you a target gun similar to those used in top level competition, I'm sure they could do it. What you'd end up with would be a gun with heavier barrels, a heavier frame, heavier wood, and through which you could shoot heavy loads. (Worth remembering here that in International Skeet, they only shoot 24 gram--7/8 oz--loads. Faster for sure than many 7/8 oz target loads, but pretty light stuff nevertheless.)

I'm sure such a gun would hang with a Perazzi or a Krieghoff in terms of punishment . . . but it'd cost a lot more because it would be a one of a kind deal rather than mostly machine-made. And if it's a sxs, the question would be whether the shooter could score as well with it as with an OU. Maybe, if he or she were sufficiently accustomed to shooting sxs.
