I was recently given an old (25 years?) .410 break action with a 28" barrel.The thing looks really rough and I dont even know if it works.It was made in Brazil and has a "FIF Corp,Miami FLA" on the barrel.Its totally gunked up and when you pull the trigger the hammer doesnt even hit the firing pin.If it would after cleaning,what the heck is it good for? Could I cut it down and use it as a "truck" gun?
