The rights holder controls how this one may be used, so the route to it runs through the publisher or the author. The source link below is the starting point, and for some in this class it is also where the instrument itself is available.
Licence classification is a research judgement by the catalogue’s authors, not legal advice, and it can be out of date. Confirm terms with the copyright holder or publisher before using an instrument, especially for commercial use.
