Brass pocket compass with leather case

I found a brass pocket compass with a weathered leather sleeve this afternoon around 2:30pm along Green Street outside the Krannert Center in Champaign-Urbana. The compass has a faint patina and a tiny engraving on the back: initials 'R.T.' The lid shows a delicate etched map of a coastline, which is pretty distinctive. The leather sleeve is worn but still intact, and the small loop for a chain is missing a tiny link. It seems like a well-loved piece, and I’d love to get it back to its owner—hope the right person sees this.
