i know Greek friends don't like the name Istanbul and not to use it , they deform it when they have to write it. I met it thousand times before on internet. A very beneficiary! idea of protesting. If the names you wrote are not this way, then sorry I don't know any of the cities you ask for information about.
About Aydin Bardakci and Crete daggers, he currently has a short Crete yataghan. A nice silver scabbarded but poor condition steel and expensive according to me.
About the Stephen Great's sword, I have seen it in real and in pictures too several times. As far as I know,it is currently being exhibited in Romania. It has been there since the last summer (if wrong, correct me). First, an exact reproduction of the sword made here was gifted to Romania, and after very short time, the original was sent temporarily for exhibition. You should be able to find its pictures on internet. If you can't, I can help you gladly, but when it returns here.
