It's definitely confusing.
The Weatherby o/u is made by SKB in Japan.
The current sxs, the D'Italia is made by Fausti in Italy.
Their preceeding sxs was made by Hermanos Zabala in Spain although that didn't work out and Weatherby switched to an Italian supplier.
Hermanos Zabala makes the current BSA and the lower-priced Charles Day imports. Zabala also markets under their own name.
You might also come across an older BSA shotgun made in England but they haven't been made for many years.
