Red enamel Dutch oven with black lid

I lost my red enamel Dutch oven yesterday around 3pm near the Billings Public Library on North Broadway. It's a 5-quart, Le Creuset-style cast-iron pot: glossy red exterior, black lid with a knob, white interior. There's a tiny chip on the outer rim and a faded sticker with '373' on the bottom. This was a gift from my grandmother, and I’m really hoping to get it back—it's sentimental and I cook with it often.
