Mach One Viola Shoulder Rest, Size: Medium

This is a Mach One shoulder rest for a viola. Size: Medium.
I used it for a while, but it often came off because it was too wide, so I switched to a Small size.
It shows signs of use but is in good working condition for normal use.
I felt it was wide for a 42cm instrument. It might be just right for someone who usually fits their shoulder rest deeply.
