My oldest is a pre-Rev War flintlock that was coursely converted to cap-lock sometime mid-nineteenth century. It's even documented to a direct line ancestor who was a surveyor, judge, and Congressman post Rev War. It has always remained in the family and has been given to the youngest male when the current owner dies. I received it in trust at age 5 when my father died at 39. He had received it not long before then, from his uncle who passed in his late 80's. After that one is my Springfield 1842 smoothbore 69 Cal musket.
