Never studied Ozark made guns , but the second part of your inquiry might be easier. The regions west of the Mississippi and south of where the Ohio flows into the Mississippi were a pipeline for guns coming down the Ohio river from the major gun building center of Pittsburgh , Pa. , and the surrounding area. Guaranteed many M/L's were built in Appalachia and eastern states , and were carried south , then west across the Mississippi. Just about any flint lock from the pre 1850's or any percussion gun from post 1850's might fit your needs. What might help is , if you could narrow down further the historical time period , you're thinking about that would be helpful.......oldwood
