From whence this Bichaq?

[motan]

Hello, mijn, like most people's, is just an opinion. Arzi however, is (almost) never wrong, and the second one is definitly Bosnian.
However, the first one looks very Greek to me. The scabbard is obviously a replacement and has a general Ottoman style-could be from anywhere between the Balkan and Syria. Originally, this type of dagger has an enrgaved silver scabbard of the same style as the grip. See picture.
