I have a ramekin and plate that I have a question about. The mark on the bottom of the ramekin is the J.P. white ware mark. The mark on the plate is the J Pouyat wreath mark, but the name is in red. I haven't seen that before (not that I have seen too much J Pouyat in person anyway.) Online all I see is a green mark and indicates dates 1914-1932. Does the red and green variation mean a different date range, or maybe a different factory or something? Or some one at the factory that day just felt like mixing it up bit?
