Silver Yamaha trumpet with initials L.P.

Hey, I lost my silver Yamaha trumpet yesterday around 3pm near Trafalgar Square, outside the National Gallery. It's a YTR-2335 with a small dent on the bell and a tiny chip on the mouthpiece. The bell has the initials 'L.P.' engraved near the valve casing, and there's a strip of blue painter's tape around the mouthpiece—hard to miss if you know the instrument. The case is black with a red lining and shows a bit of wear from travel. I’ve been practicing for Grade 8 and this instrument means a lot to me; really hope it turns up soon.
