The Browning Superposed Broadway shotgun is a variant of the popular Browning Superposed Over & Under double barrel shotguns produced in the late 1950s and 1960s (possibly as late as 1975). These shotguns were primarily intended for trapshooting and the "Broadway" term refers to the wide sighting rib (5/8" wide) running the full length along the top of the upper barrel. Standard Superposed shotguns typically had a rib 3/8" wide.
The Broadway superposed shotguns were 12 guage (12 bore) with 2 3/4" chambers (3" magnum loads will not work in these guns and it is dangerous to try). Typically they Broadway trap guns had 30" or 32" barrels although it is possible that some custom lengths could exist. The original barrels had fixed chokes, usually modified, improved modified, and full in a variety of combinations with the most common usually being modified on the lower barrel and full choke on the upper.
The Superposed Broadway shotguns were all made in Belgium and are exceptionally fine firearms. Many are still in use today by competition shooters despite being more than 40 years old. Some have had hundreds of thousands of rounds fired from them.
Browning produced Broadway Superposed shotguns in a variety of finishes including the Midas Grade which included heavy engraving and gold inlay.
