Is this a naval issued Luger?

Norm/others -

Is there any significance to the dot between/beside the "N" and the rack number on the backstrap???

Is this common among Naval or other 'racked' German weapons???

Hi Rich, I think that "period" is just a slip on the part of the pantograph operator. Most Nazi era marks do not have periods. Those Naval property marks were not applied at the factory, they were engraved at the dockyard, sometimes rather carelessly.
