Silver harmonica in black zip pouch

I lost my silver harmonica yesterday around 3pm near the Market Hall on St Peter's Street in Derby. It's a well-used Hohner, the chrome has a couple of tiny dents near the cover and one small scratch by the mouthpiece. It sits in a black zip pouch with a bright red interior, and there's a faint coffee stain on the pouch from last week. I even wrote my initials PP on the inside label so I wouldn't misplace it again. It really means a lot to me—it helps me unwind after late shifts, and I'm really hoping to have it back.
