Offered is this very interesting Heer pattern zeltbahn.  This example is mostly complete and free of major damage or repairs.  It is an earlier example with all aluminum hardware.  What is most interesting are the markings, in particular the 2 Esk.    This is a bit difficult to decipher with no other context, but based on the U.S. Army compilation of German military abbreviations, this could be 2nd Eskorte (mounted convoy escort) or the 2nd Eisenbahnsonderkommando (special railroad service command).  Very nice zelt.
