Lost vintage violin with scratches in a dark wooden case with golden interior at Kalamazoo State Theatre.

I lost my grandfather's vintage violin while attending a concert at the Kalamazoo State Theatre last Saturday. It has a few notable scratches on the body and is in a dark wooden case with a golden interior. I was sharing my seat with a friend and didn't realize it was missing until I got home. Please help me find it, it holds a lot of sentimental value.
