Need more info. If the dating is correct......Nitro special, 26-32 inch barrels, varous chokes, box lock, extractors, checkered pistol grip stock.
Condition determines value....from $200 to $450.
Add $75 for single trigger
Add 20 percent for 16 ga.\
It should not have auto ejectors, just extractors if date is right.
Hope this is some help.
