To begin with, it should be noted that at that time, Greece did not exist. However, there were Ottomans of Greek descent, very good at their job. They were located throughout the Ottoman territory, in some villages even as the Kallarites of Epirus almost 100% of the inhabitants were silversmiths. (The VULGARI international house for example started there.) Unfortunately, though we have a multitude of silverware in monasteries with their manufacturers' signatures, this is not the case with everyday objects such as weapons, jewelry, etc.
Thus, we cannot safely attribute the Nationality of an object, especially before 1821, when the Greek Revolution began. It may not sound scientific at all, but only with the experience of visiting as many museums as possible in the areas of the former Ottoman Empire can we attribute (always with probability) an object to Greek, Turkish, Albanian, Montenegrin or Armenian craftsman.
In this case, the photos do not help in any comparison, but I do not think the manufacturer of the scabbard is a Greek one.
