Thank you for viewing. This is an Italian-made shoulder rest for a Y. Menuhin 'STUDENT' model violin, size 4/4. I received this for lessons but am selling it because I switched to a different shoulder rest. It is no longer in production, so if anyone was looking for one, please consider this. There is some slight deterioration from use, but there are no noticeable odors, and I think it can still be used without any problems. - Model Name: Y. Menuhin 'STUDENT' - Country of Manufacture: Italy - Patent Information: PAT JAPAN 207153, PAT SUISSE 302943, DEUTSCHES PAT 950424 *Please note that as this is a private sale, we cannot offer returns or after-sales support.
