probably 1970's or so. Dixie gunworks had partially inlet stock blanks and you could pick and choose pieces and assemble your own rifle. The parts don't match and the workmanship not too great so I would suspect it is something like that. Does the lock fit tight to the barrel? It looks like it is only partially inlet. If it is not tight to the barrel priming powder can get behind the lock with disastrous results if it touches off.
