Well that looks a beautiful bass.
I visited his workshop in Germany a couple of years ago. He had lots of different models, they all sounded good, but different from each other.
If it's by him it is going to be good, but you need to play it to see if it does the things you want it to. One of them I really liked,great for jazz, but bowed well too. Others were big orchestral beasts, sounded louder at the other end of the room.
Good luck
