I know the top ones are made in Belgium, and the bottom of the line are in Japan. But can someone list where other lines of Browning O/U are made?

Let me kindly correct a statement you made... "the bottom of the line are made in Japan". I own two browning O/Us. Both were made in Japan. One is a Citori Lightning Grd VI and the other is a Ultra XS. The grade VI is over $4,000.00 at many dealers. Do you call that bottom of the line? The Grd VI has absolutely beautiful wood on it and the XS looks great too. I shoot sporting clays and have seen many shotguns and not many in any price range are much better than my Brownings. I also own a Beretta SP V and a Weatherby shotgun and neither, although nice guns, compare to the Brownings.

I have four or five Browning O/U's and A-5's with a couple of the latter being Jap and two Browning O/U's being Belgian. I gotta check up on the rats every so often to see which of what it is that I have. At a decent price I would never hesitate to buy another variant. Belgian Brownings are still made on special order and in their fancy form run about $18,000. At least one importer can order them.

Thank you both for the info.

The Browning Superposed line has been made since the 1930 by Fabrique Nationale (FN) in Belgium. Another FN-produced line was the Liege or B-26/27. The Citori line is made by Miroku in Japan.
