The markings on all of them are the same. I will try to describe them the best way I can.
On the left side of the magazine it says " PB CAL. 9 PARA MADE IN ITALY"
On the back it has 3 holes marked 5, 10, 15.
On the right side of the magazine it says "ASSY9346413-65490"
That is all the markings on them. The finish is not the best, maybe a 65%. I couldnt tell you about function. These were used in OEF by my buddy in his sidearm.
