More thanks. Useful recce in Selfridges today. There's a sale on btw. And they now stock Knomo. Very nice selection of bags from Mulberry but no loop or sleeve to slip over the handle of a rolling case. Mandarina Duck looked nice quality but not all the range was there to try. Some good-looking, practical and affordable leather stuff also from Jost, but messenger bag style only, no handle. Tumi present in quantity but not the Georgetown, sadly. Still, this all provided some very useful hands-on testing time.
