Jug with strange numbers, but German lava it seems

I bought this jug last sunday, but until now I can't figure out which company was responsible for its production. To me it has strange numbers at the bottom: 902 12 19.
Ok, the last '19' is probably the height. '902' the shape? What does that '12' stand for then? More important: which pottery made this?

Now I'm pretty sure this could be Jasba , that's the sort of numbering with them , no doubt I'll be wrong again , Ed

here it is with an "N" in front of the numbers .

I suddenly remembered I bought the day after that a pot with Jasba marks:



With '19' probably the diameter. Once again raises the question: why all these other numbers?

You're right, Ed. That's the jug. That one also arrived in the Netherlands, I see.
Thanks for the ID. :-)
