Hi, unfortunatly the battery of my phone was quite dead: next week I will go to the shop and ask to take some photos.
I think the bolt is mismatched, but I'm not sure because it has no farsi character (it has only a 3-digit number) and I cannot compare it with the farsi serial on the receveir. On the receveir there is also an alphanumeric serial stamped by italian proof house: it doesn't match with the one on the bolt, but I can't say if it is a translation of the farsi serial or an arbitrary one choosen by the proof house...
