I don't know how much hand fitting is required to justify calling a gun "hand made" but I don't think the Superposed guns were ever "hand made". Not much has been truly hand made since the late 1800s, IMO. Other than the cheapest cottage industry junk from Spain or India or maybe some other 3rd world countries. Most of the better guns have been made using a lot of machine work for well over 100 years. As to being a "Belgian made Citori", the Citori didn't appear until the Superposed had been on the market for over 30 years. So it might be appropriate to call the Citori a Japanese made Superposed, but certainly not the other way around. Joe Shiozaki, maker/installer of Air Cushion stocks, served his apprenticeship at the Miroku factory. Joe has stated that the Citori, at least the early ones, are better made or better designed than the Superposed.
