Just wondering where the case serial number comes from, as the only one I can see on the case back is "3 - 61631", with some scratches next to the last number that look vaguely like an "8". This can be seen a little in my screenshot, but not very clearly, much better to zoom in on the actual picture above. Underneath can be seen the date mark, N3.
