Gilded brass, edition W with imperial crown.The officers of Oldenburg and Baden wore the buckle with the imperial crown over the cipher (WII). (Die Offiziere von Oldenburg und Baden Feldbindenschloß) D.R.G.M. No 115221 The acronym D.R.G.M. with or without punctuation stands for Deutsches Reichsgebrauchsmuster, meaning that the design or function of an item was officially registered inside all of the Germany states and not only locally registered as it was the case before the introduction of centralized registration. Note that many people quote this acronym as standing for Deutsches Reich Gebrauchsmuster, which is grammatically wrong and also ommits the letter 's' after Reich. This results in shifting the weight of pronounciation on 'Deutsches Reich' alone, but this acronym has nothing to do with the Third Reich as many sellers want to imply so to catch the attention of certain 'collectors'.
