1903-1939. Value depends on condition. Your definition of excellent might not mean excellent in terms of collectable Browning shotguns. Broad range; a couple of hundred to a couple of thousand.
Depends on what configuration. The Broadway Trap was available in Lightning, Field, etc, in the Superposed.
