This is a seriously heavy piece by the look of it and I would sooner place it in Poland or Czechoslovakia. Reason is the weight, the uneven way the outer layer meets the inner, the thickness, the robust bottom finish and the contrasting clear handle.
The contrasting clear appliques and handles are to me unmistakable. I am not venturing a factory but I would not be surprised if this is from Tarnow or Prachen....
