antique firearm

Need some help identifying this antique. It's been in the family for generations. Also looking for recommendations to have this piece refurbished.

Hello all, new to this forum but I am pulling my hair out trying to identify a rifle I purchased, it is from the year 1600.. the lock is gone so I do not know if it a wheellock or a matchlock. I have been looking for what name this could be or where it came from… hopefully both. Yes I am aware...
