Joe:
In 1951, the West German Ministry of the Interior of Lower Saxony contracted with Star to supply their police, the Landespolizei Niedersachsen, with pistols. Amoung other markings, the front gripstraps of this contract were to be stamped with the initials, LPN. Approximately the first 2000 pistols, if recollection serves me, of the contract were made up of Mdl B's that had been procured by the the WWII German military but had not been delivered due to the invasion of France in 1944, thus preventing delivery. These pistols were in the serial # range under 260,250. These pistols would not have been German military acceptance stamped as there were no German inspectors stationed at the Star factory, rather, the pistols were acceptance stamped at the German Military Depot in France upon delivery. At least that is what credible references tell me.
