Answer 1

late 40's early 50's.The Browning superposed grade I lightning was made starting in 1936.They came with striped barrels-ribs were extra.the original butt plates had 2 intertwined circles and were made of horn!If you have this,and the fact that serial number 1246 was apart of the first year of production(1-2000) plus a Twin single trigger all indicates that your Superposed lightning is a first year production shotgun.It also must be chambered in 12 gauge.If you have a 20 gauge model,then it was made in the year 1949.
