There are a couple of noticeable flaws - please see ALL photos and ask any questions you may have, including requesting more detailed photos.I have only put this together and played a scale (the limit of my ability on the clarinet). I don't know that it functions properly or what, if any, repair work needs to be done to it.The case is from a shop called Casa Musicale Sanfilippo in Messina, Sicily, Italy, though I'm not sure that the clarinet is also from there.I will also include the mouthpiece and pot of cork grease that are shown in the pics.
