Who made the model known as china blue grapes in the 1800s?
There is a pattern called China Blue Grape by Addersly China. He was a model from an old Sheffield Pottery pace since the 1800s. I purchased a set that dates back to 1830 but no brand manufacturer. Does anyoneknow who has done or what is its value?
That is also a cause of classic Wedgewood.
