The plastic one, 3L in Lidl or Tesco, 2L in McLoughlin's. McLaughlin's is the only one I've come across so far that says "see code panel" or some such. In that case the code panel was the lid where I found the code 1405 which I could interpret as Glanbia, Drogheda thanks to the SS you posted. Glanbia is, of course, Avonmore. I think the Drogheda plant used to be part of Dundalk and Drogheda Dairies in the good old days.
