Small brass compass with leather strap

I found a small brass compass with a dark brown leather strap this morning around 11:15am on the MSU Billings campus, tucked under a bench by the library along University Drive. It's about 1.5 inches across, with a warm brass patina and a tiny compass rose etched on the lid. A faded green nylon thread loop is still attached, and the glass face has a light scratch but still looks usable. I left it on the bench in case the owner comes back this afternoon, hoping it finds its way home. If this sounds like yours, share a couple distinguishing details and I’ll get it back to you.
