It used to be that all such old guns were automatically consigned to the scrap heap or to the status of wallhangers, and that's where some of them certainly belonged. However, some were well-maintained and are still in surprisingly good condition today. If yours looks good and the barrels are tight, I'd have it looked over by a professional gunsmith. (I'd never fire an old gun that a competent gunsmith hadn't approved for shooting, especially not one with Damascus steel barrels.) But, assuming "the trigger section" can be restored for reasonable cost (which is a big "IF"), you MAY have a fine old shooter there that will do just fine with blackpowder loads or, if it'll fire shotshells, you may be able to use "vintage" smokeless loads (which can be purchased from some specialty shotshell manufacturers, or can be handloaded).
