I find someone who's close, but apparently not close enough:
Major z.D. Rauthe, (1909) kommandiert zur Dienstleistung zum Landwehrbezirk Metz with RAO4, DA, BZ3bE, PGr3. No KO4, which is odd. Odd anyway the BMV4X on this bar.
Unless... some of the awards are replaced for higher grades, that were missing? Could someone check between 1909 and 1912 (he isn't listed in 1913 anymore).
I could imagine he won a KO3 in the meantime, was reactivated for the war, won a BMV3X...
It's just an idea! BZ3bE with PGr3 is just too unusual on a Prussian officers bar. I can hardly imagine there were two with it.
