UV filters from Leica

[Scheelings]

I bought my M8 second hand, however I'm not sure whether the original owner claimed the 2xUV filters that came with it. How do I determine this?

Register the camera at Leica www and somewhere inside there is option Bonus or something like that (dont remember it correctly, I had M8 two years ago).
There you will see if the filters are available for your camera SN.
