First- welcome! Glad you found your way to us!
Second, we need good, high pixel closeups of all sides, and any markings. Right now, can say this appears to be a turn-barrel caplock pistol- barrel unscrews, is loaded with a lead ball, loose powder, screwed back on, and a percussion cap placed on the nipple. Cannot offer much more without more info from you.
What we have here is... failure- to communicate.
