Very interesting set that comprises 3 x  Waffen Feldpost letters with their matching envelopes sent in 1943 to his wife by an member of the Waffen SS-Mann from an SS batallion based in the occupied Polish city of Warsaw.Most probably these were sent by a member of Waffen SS garrison that was in Warsaw Ghetto. This SS battalion took part in the liquidation of the Ghetto Uprising. All with ink stamp of the Waffen SS. Good condition.
