Silver Yamaha trumpet with blue sticker on case

Yesterday around 6pm after rehearsal on the University of Montana campus, I realized my silver Yamaha trumpet was missing near the UC loading dock behind the University Center. It's a silver lacquered brass horn, a bit worn with a tiny dent in the bell and a scuffed third valve slide; the mouthpiece is a standard 7C. It comes with a black hard case lined in blue velvet, and the case has a bright blue dragon sticker on the outside. This instrument has sentimental value for me because it was a gift from my mentor, and I really need it back for upcoming gigs with the Missoula Jazz Collective.
