One of the Forum members on whitefriars.com had a set of these (came in mixed colours) which had label on "Made in Italy". I am assuming yours is one of these. The rim does look much thinner than on a bark vase, and the "crimped" section at the top is definitely not indicative of a Whitefriars bark vase. As for a definitive maker, I just do not know. As a matter of interest, what is the diameter at the top?
