Well, it surprises me that anybody brought it up yet, but i have a similar example in my collection wich was discussed here some time ago.
It is definetly a weapon of the same type, but lacking in decoration. and it is definetly an old flyssa! Ham, the pictures above could be deciving. The determinant factor is the tang.Yataghans have a full and wide tang, wich flyssas have not. Look at the notch on the backedge, another typical flyssa sign.
