Gold trumpet with dented bell near Millennium Bridge

Found a gold trumpet this afternoon around 3:45pm, resting on a bench near the Millennium Bridge by the Quayside in Newcastle upon Tyne. It's a standard Bb trumpet, brand looks like Yamaha, with a noticeable dent in the bell and some worn lacquer along the slide. No case was with it, but I did spot a small sticker on the valve cap that says 'M. Collins'—could be a clue if you know the owner. I held onto it for now, hoping to help a musician get it back soon. If this matches your instrument, describe the dent, the sticker, and the brand to verify.
