stallzer - you are right that the image might be difficult to plate from, however, this one is actually quite easy.
First - its a modified T relief, which means top row Plate 1,2,3.
Second - its recut at bottom, so its Plate 1-Late.
Third - The modified T relief on 1L is 1-10L, and 1R, 2R. 1R and 2R are easy to eliminate so its clearly top row left pane 1L.
Fourth - The big dot between ornament F and G is a dead giveaway. That narrows it to position 3L1L or 6L1L. The orientation of the dot points only at 6L1L. Also, I can see some of the doubling at top right by ornament Z.
