Lost silver flute with small dents and unique engraving near the riverbank picnic spot in Lancaster.

I accidentally left my silver flute at a picnic spot near the riverbank in Lancaster last Saturday. I was playing music with friends, and it must have slipped out of its case while I was packing up. It has a few small dents and a unique engraving on the foot joint. I'm really hoping to get it back; it's been with me through so many performances.
