Red harmonica with blue KM sticker

I lost my red Hohner Special 20 harmonica yesterday around 3pm near the Port Huron Station on Military Street. It’s a red plastic-covered 10-hole harmonica in key C, with a small dent on the lower edge and a blue sticker bearing the initials 'KM' on the top cover. It lives in a tiny black pouch with a faded sun sticker. It matters to me—it's the instrument I grab when I’m stressed, and it was a gift from my grandmother. I’m posting this under the Miscellaneous Musical Items section, hoping someone who finds it can return it. If anyone found it, I’d really appreciate getting it back; I can meet up downtown to pick it up.
