Lost & found wind instruments in Bristol

Gold Yamaha trumpet with initials A.H.

I was at a Bristol Jazz Collective rehearsal yesterday around 3pm and realized my gold Yamaha trumpet went missing. It's gold lacquer, three valves, with a slightly curved bell, and it's in decent shape aside from two tiny dents near the bell and a small scratch along the third valve slide. The mouthpiece has initials A.H. engraved on the rim, and I always kept a bright orange cleaning cloth tucked in the soft black case. It's a gift from my late mentor and means a lot to me, so I really need it back. Last seen outside The Arnolfini on the Harbourside near M Shed, around 3pm yesterday.
