The original German markings were scrubbed and replaced by the Yugoslav ones. The most noticeable markings are the Yugoslav Crest and the "Preduzece 44"(It refers to the site where it was refurbished; for example "Preduzece 44" stands for "Institute 44"-Kragujevac, Serbia-the current location of Zastava Arms) present on the receiver's ring. Another noticeable marking is the one present on the left side of the receiver, the "Mod. 98/48". The "/48" is absent on all the rifles that have been refurbished before 1950.
