Lost vintage trumpet with some scratches, possibly dropped near the fountain bench at Inland Empire park.

I lost my grandfather's vintage trumpet while out walking in the Inland Empire park last weekend. It has a few scratches but is overall in good condition and has a warm sound. I think it might have fallen out of my bag when I was sitting on a bench near the fountain. I'm really hoping to get it back as it holds a lot of sentimental value for me.
