Lost black clarinet with a small scratch on the bell, left on a bench by the lake in Hermann Park.

I lost my black clarinet last Tuesday while walking in Hermann Park. I think I left it on a bench by the lake. It's a bit old but has sentimental value since it's my late grandmother's. There's also a small scratch on the bell. If anyone has seen it or picked it up, I'd really appreciate a shout-out.
