That is a neat detail Bob. Several years back, I bought an assortment of 13U memorabilia out of Germany. I assume that it came from a family who were not really interested in the military history of a long gone relative. Included was a type written history of a battle (in German of course), two pair of metal epaulets, a couple of photos of the trooper, a shooting award, a couple of tin badges from a later reservist meeting and the subject photo. I have always assumed that the drummer photo was of the trooper to whom all of the other stuff belonged. Overall it was a great catch. I don't read German so I don't know what it involves. The title is: Schilderung eines Gefechtstages/ vom/5. Konigs-Ulanen-Regiment 13. Przesiadlow, 12.2.1915. Translation? I forgot to mention that the haul included a three volume set of books on the history of the 13.U Regiment.
