Can only see Loake from the thread/link.
Loake, C&J, EG are just the standards. Ferragamo is interesting as well.
JLP is less informative but a very good marketing tool. JL St James interview by The Guardian is interesting as well.
Saint Crispin's video clearly shows how they are a notch above most if not all English RTW shoes makers.
One of the most surprising video is from LV; they apparently make hand welted shoes of very high quality even when I don't remember seen any in their stores.
