I forgot to mention it was purchased in France, and I appreciate your help! I'm sorry to say that I'm not familiar with Mike Hunter work, I googled him and his work really looks amazing, but I don't think it's him, would he leave unfired rim? I agree that ware could be accumulated very fast and that it is a bad measure of age, even absence of any means nothing, there are 100 year old pieces without a scratch.
to me it looks kind of Art Deco, shape looks venetian, technique venetian but execution bohemian, but I have no idea who could have made it and if any of my guesses are correct.
