Can Someone Please Help me identify?

Can someone please help me identify the origin of this Flintlock or at least give me a few pointers? My dad bought this at a garage sale when he was a teenager and has had it stored up ever since. I got my hands a hold of it, and don’t even know where to start. It looks legit to me there is idolization On some of the metal piece. and inside the barrel looks pretty old, but I’m not an expert and thought I could use some help. Thank you very much!
