Green jug - Rye Pottery? Ubeda Pottery?

Sorry no photo of the base but it’s the same shiny dark brown glaze as the interior , I think with stilt marks but no marks. I’d seen it earlier and thought it might be Farnham but various things like the handle made that unlikely so put it down thinking it might be Belgium or Spanish but then wondered if it was more likely to be British. Ubeda Pottery, Spain is a possibility . Took the photos through the charity shop window when I went back. Maybe Torquay or Rye?

None of those, the black interior is wrong.
