Hummm...First off, is the holster brown or factory dyed black? Second, is it cut for and/or has the lift-up strap? The earliest marked holster I saw/had was kind of a "oxblood" color. The marking was a rectangular "Eagle/WaA77" between the belt loops. This marking is the same die pattern seen inside K98k buttplates stamped on the brown anti-rust paint inside. Most earlier holsters are ink-marked "bnz". Some few are die-stamped "fuq"and 1942 (maybe 43, too) between the belt loops. Getting into late 1944 and '45, the lift-strap was omitted (although some holsters will have the slot punched for the strap but it will never have been installed). The late codes are "grz", gaq, and I believe "ror" (the latter likely being a revised code for "grz"). Examples of dates are "grz 194", "gaq 4 or 5" and the late "ror" most likely dated for 1945. The holster has a code never before encountered on such a item. The German code directory identifies "gxz" as belonging to Ernst Heinkel, A.- G. Werk Jenbach/Tirol, it. 8. Nachtrag and we know what they made! This is not a "lederwarenfabrik" which typically produced such items. Looking at the inconsistencies of the ink marking and 1943 date, IMHO someone free-handed this with a ink pen in an attempt to deceive or possibly embellish a very weak or partial original marking. That individual was not aware of the actual known, authentic manufacturer codes/dates either...
