Jan, here is a scan from the Neinken book showing the recutting variations from plate 1L.

For your stamp, we know it's a type A by the ornaments on the top left and right having their tops erased. On the diagram, the heavy black boxes correspond to relief A. Looking for recut twice at top and once at bottom (which is what I think it is) we see the stamp could only be position
51L,
60L,
71L, or
77L. We can immediately rule out 71 as that position has an inverted double transfer, which you would be able to see as some lines running through the ornaments on the top and bottom left.
The actual plating requires a level of detail not visible in your scans, but you can look at examples of the positions at
Slingshot Venus and compare them with the real thing. That said, I think it might be 51L1L as I think I see a slightly curved line running through the upper left.
