Lost dark brown hard violin case containing an antique violin in Riverside Park, Corvallis.

I lost my violin case on Wednesday while walking in Riverside Park in Corvallis. It's a dark brown hard case with a few scratches, but the real treasure is the antique violin inside, which has a unique design and weighs around 1.5 pounds. It holds sentimental value for me as it belonged to my grandfather. If anyone has seen it or picked it up, please let me know – I'm really hoping to get it back!
