this is a good starting point.
i was given a persian mauser by my father in law about 1 month ago. he got it from samco, it is the unissued grade and came with a 'qualifying target'. it was used by the iranian army to test qualify a batch of guns before purchase. my targets show 4 holes in a 5x5 square. it is signed by the shooter, brno reps, and has a seal i can not make out. it is in beautiful condition. let me know if u have any questions and i can send some pix if u like but my rifle looks exactly like the ones on aliparsa.com
