Yesterday I attempted to put these PIC's on, I was unable to, & deleted that "reply". My prior post mentioned the differences of the CSZ & Persian made bayonets. The rivets attaching cross guard for one. The press stud shaped differently. Most obvious are the small crescents on the grip bolts, and behind lower cross guard. Finally, the inside of King's Crown. The CSZ has an "X", the CSZ an "O". Hole these PIC's come out this time! I spend a great deal of time doing them.
