Looks like the wisdom of the stooges is well placed! I think the score for birth of the karabela is to Turkey by landslide with only one shaky example for the Iranian claim. You perceived my comment pertaining to the Khorasani reference well
Outstanding research there as well Ariel. I do agree with Teodor also in wondering if the Selim sword is a remounted example in the manner of many of the Topkapi swords.
All the best,
