Hi,
I was wonerding if anyone might want to take a guess on where this sword came from.
Here's all I have:
A short sword

late Roman/early Age of Migration, 4th-6th centuries A.D.
Double-edged blade with slight central ridge, the lower half of the blade heavily corroded. Short, sturdy quillons with lateral surfaces narrowing towards the blade. Flat tang with mushroom-shaped, slightly ridged pommel. Cleaned water find. Length 62 cm.
Rare type of sword, which documents the transition from the late-antiquity gladius to the early medieval mushroom-pommel sword.
It was found in East Europe.

Its roman-ish, which group of people might have created it and used it?

Thanks
Steve
