Brass pocket compass with leather sheath

I’m hoping someone found my brass pocket compass, about 2 inches tall, tucked in a black distressed leather sheath. It has a faint compass rose on the front and the initials 'M.P.' engraved on the back, plus a tiny red thread charm dangling from the belt loop. I last had it yesterday around 3pm, outside the Starbucks on Market Street in the Gaslamp Quarter, downtown San Diego; I must have dropped it when the crowd got thick. The brass is a little worn and there’s a small scratch near the edge, but it still works. It’s sentimental — it belonged to my grandfather and has traveled with me through many trips. If you found it, please email [email protected]; I’d be so grateful to get it back.
