Upon closer examination of your photo, I can see the cover plate, and the edges of the charger guides at the rear of the receiver-so it's an 88/05. A lot of the '05s were sent to Turkey. If you look at the rear sight markings, and they're some sort of Arabic markings, then it's a Turk one. Also, the bolt will have been replaced. They arrived in Turkey without bolts, Turks contracted to have new ones made. Anyone looking at one, be sure the bolt head is present! It's a separate piece, and apparently lots of them were removed when the rifle was used as a Wall Hanger.
