I'd add some of the Mercian models, I think King of Mercia, and the Woodrup Giro Touring. One has to be careful about the Woodrups, because they seem to have used the same nomenclature for a wide range of geometries. But my early '80s model has 44 cm chainstays, 56 mm fork offset clearance for 700x 32 tires with mudguards, decent front-load handling, and 73/74 head/seat angles. It has a cushy fork, but a pretty stiff rear end, with stout 18 mm seatstays. I'd expect it's at least as stiff as a Trek 720 tourer.
Bob Jackson also offerred touring models.
A little more modern, one finds Charles Roberts frames. I've seen one, but I don't know much about them.
Even more modern, Bruce Gordon Cycles.
Staying in the UK, Thorn and Dawes currently offer tourers, and there's still Koga Miyata.
I don't know what's C&V and what's not, but the Trek 520 is both current and not current. Same for Woodrup, Mercian, Koga Miyata, and Bruce Gordon, not to mention many more.
