I popped into Hastings Museum on Saturday to check and I was right, they have a jug almost exactly like the one i bought. Slight difference to the spout and the banding and handle. I'm fairly confident it's from the same pottery, Rye Pottery. it says from around the mid 19th century for that one. It's condition is obviously better, but I'm glad i found it's brother! Beautiful isn't it? quite a beast though, not sure how folk picked this up full!!... well you can tell they didn't really, as there is particular wear on it's belly bellow the spout where it's been tipped repeatedly. It's great how they tell you their stories isn't it.
