Blown Gl Bird/Duck/Swan?

Hi, I have a blown gl bird. Not sure if it's a swan or a duck.. I'm trying to find out if it's an antique but I cant find it anywhere online. I saw some hand blown gl swans made by the company Murano that look just like it but their lable doesn't match mine. My lable is silver and has a man rowing a boat on it. That's all I can find on it, there's no other inscriptions. Can anyone help me? Do you know the maker of gl birds that has a man rowing a boat on it?
