Red pocket metronome with blue star sticker

Yesterday around 3pm I lost my red pocket metronome somewhere near the Boston Public Library on Copley Square. It’s a Wittner-brand tiny metronome, about the size of a matchbox, with a white pendulum and a blue star sticker on the back. It lives in a small black zipped pouch that I keep in my drum bag, and the pouch has my initials 'P.P.' embroidered on it. This little device means a lot—it's a gift from my college music professor and helps me keep steady tempo during rehearsals. If anyone found it, I’d really appreciate getting it back.
