Black leather briefcase with red interior

I found a black leather briefcase this afternoon around 2:15pm in the lot behind the Union Pacific Station on 1st Street in North Platte. It's about 15 inches wide by 11 inches tall, with a worn top corner and a brass zipper pull. The interior has a bright red lining and a small brass tag engraved 'RS-47'. Inside the main pocket, there’s a blue fabric key fob and a faded MarTech Solutions business card, just enough to hint at the owner. If this looks like yours, email me at [email protected] and we can arrange a pickup near the station.
