Please help me find a brooch lost in Cologne

I'm Vanessa. I lost my late brother's brooch about a week ago, somewhere between the station and the bus stop. It's a thin gold band with a tiny engraving inside. It isn't valuable to anyone else, but it's one of the last things I've of brother. I've retraced my steps twice and asked at the shops and the bus company. If you've found it, or you have a bin, a bench or a hedge you could check, I'd be grateful. A finder's thank-you is waiting. Please use the offer button here rather than sharing any numbers publicly.
