At the opening of this episode, two German soldiers were ambushed by some partisans, one of the soldiers shot back with a K98, we can clearly count 8 shots in a row, however K98s use 5 bullets clip.
While escaping from the partisans in a VW Kübelwagen, the Kübelwagen has a hubcap on its spare-wheel that was only produced after 1949 (round hubcap with small VW-Logo).
