I agree, it looks "real", i.e. not just wall decoration. The blade shows some Ottoman insignia and coat of arms (and could be european trade blade, such as Zolingen. Any stamps at the base by forte?). The hilt is retrofitted Karabella-styled, also Ottoman type hilt. The later crossguard of that form is not unusual, although not common. It is impossible to determine without seeing it complete, can wee see the whole sword, and how about other two swords?:-)
