Oldest dated flyssa - appeal to EU/Spanish forumites

[Wodimi]

Hi Emanuel,

I just found your interesting thread about the Flyssa, it seems you have much knowledge in this field.
Have you, or any other member ever found or seen a Flyssa with such a wide blade? Length is 79 cm and at the widest point on the blade short over 5 cm. It is also not so pointed, as a Flyssa normal is, but real heavy. Could it be that it was used for a special function? I have a theory, but would like to hear first if somebody would know something.

Thanks
Wolf
