Hi Rosie, I steer clear of this type of jug and always say "I don't do jugs"! Unless I just want one for the home for water or lemonade. There are just too many "wannabees" of very similar shapes to the Whitefriars ones. If however, you are determined to find a Whitefriars tall jug, then the best thing is to spend a LOT of time looking at the catalogues, making note of the catalogued colours and position of handle etc. Some of the many Polish or Italian makers made loads of similar jugs, but there is always a slight shape or handle position which differs from the WF ones in my experience. And many of the foreign jugs also had a polished pontil mark which of course to many people ONLY signifies WF when it does not - of course you know that but loads of people do not.
