James H - Mike - I now think that this jug was made at Askrigg Pottery by Andrew Hague. That was the name I thought when I first saw the mark but the work looks so different to his other work that I have seen and handled. But as always (and as if often the case), I could be wrong.
James H - I have now had it confirmed in a very kind email from from Andrew Hauge that the jug was made by him.
Thanks as always Mike for your kind help with all these unidentified pots that you post for people. Its a great service and its so kind of you to give up your own time to help. I am sure that everyone appreciates it as much as I do.
gabrielle - i confirm that jug is from Andrew HAGHE
