From the look of it, I am not very enthusiastic about overall appearance, the ring, especially on the reverse side, the writing on the front. Seriously better scans are definitely needed if you want anything better in term of feedback.
Matthijs,
Also, if at all possible, have it measured and get it's weight. As everybody here says, you do need to be very careful with this one, it's tricky.

It looks like the one I`ve seen on E**Y a few weeks ago. The ring is too thick and has no grind marks. I also cannot recognize the "fingerprint" of this medal...doesn`t look good :(
