[G.T.]

Hi Jon! The correct way to register your Luger is to use all the information available to you....so, for example, I would write a serial number as follows (hypothetical, of course) byf 41 6xxx a ......that should do it! Your safe unless they repeated the serials and the codes during production, and that would be rare, if not nonexistant! till...later....G.T.
