Hello Everyone ! Few days ago I bought used one but it was never played and it was bought from schreiber few years ago so basically it's like new.Everything is great,no leaks,cracks in wood...perfect basson ! But I was wondering is this basson actually clasified as profesional like moosmann 222,200,150 or puchner 6k or 5k ?

Yes - they do list it as a professional instrument.
