Silver Yamaha flute in blue case, initials ZA engraved

I lost my silver Yamaha flute yesterday around 3pm outside the Tate Modern on Bankside, along the South Bank near the Millennium Bridge. It's a silver Yamaha flute, model YFL-281, with a small dent near the foot joint and a blue hard case that has a white Yamaha logo and a slightly frayed strap. The lip plate is engraved with my initials 'ZA'. The case is a bit scuffed, and there's a tiny sticker that says 'University Jazz' on the interior lid. It means a lot to me—it was a gift from my grandmother and I relied on it daily for lessons. Please reach out if you've seen it; I'd be so grateful to have it back.
