This type Mauser was my very first milsurp purchase. Got an unissued one with bayonet (longest bayonet out there, I think). I eventually stripped that tacky shellac off and rubbed on Minspeed for a flatter/more satin look. I also added a MOJO rear sight aperture. The protective ears on the front sight disallow mounting the matching front aperture, but the MOJO system still works - centering the front post in the rear aperture. I had a guy who speaks Farsi translate the markings for me. On the butt, indented in the wood, there are the unit type markings. Mine was an Infantry unit. On the side of the receiver will be the date of manufacture. Even though these were produced by the Czechs on German tooling, the receivers and ladder sights are in Farsi. Also, the Persian calendar system is used to date the receiver, so you'll need someone who knows that calendar to figure out what year it was made. This one of my longer rifles - especially with that pig-sticker bayonet attached! Contemplating mounting a scope ("Scout" style). Should be a good shooter. I look forward to your photos.
