Browning U.S. headquarters are in Morgan, Utah, but they never manufactured a BSS there. There were four basic series, all made in Japan. The first series had a Silver colored non-selective single trigger. The second series had a gold colored selective single trigger (mechanical). They were available in the standard configuration with a pistol grip stock and a beavertail fore end, or Sporter configuration with a straight stock and a semi beavertail fore end. Towards the end they made some sidelocks in either Grade 1 or Grade 2 if memory serves. They are all quite well made guns in the American rather than the English style, although the sidelocks are little bit closer to English guns than the boxlocks. They now sell for about 4 to 5 times what they were selling for new, when production ended. I have a selective trigger Sporter 20 that I dearly love. My stock is a LOT darker, and with less figure, than the gun pictured above.
