While the Brit boxlocks of the 1920's may well be better guns, they're also at least half a century older guns, and they were not built to withstand the pressures generated by modern American 2 3/4" shells. So whether an old Brit boxlock is a better gun depends on several factors, a very important one being what you intend to shoot in the gun.
Note that I write the above as a fan of British boxlocks and as the owner of a pair of 1933 vintage Army & Navy boxlocks made by Scott. But one does have to understand their limitations in the 21st century shooting world.
