Small brass pocket compass with red cord

I lost a small brass pocket compass with a red paracord string yesterday around 3pm near the entrance to Grand Central Market on Broadway in Downtown Los Angeles. It's about 1 inch tall, with a slightly worn brass finish and a tiny dent on the lid, plus a brass engraving of a compass rose on the back. It was on a keyring with a faded green rubber grip I use for my backpack zipper. It has sentimental value—my grandfather gave it to me before he passed, and I really need it back. If someone found it, I’d be grateful to have it returned; it feels like a piece of him is missing when I don’t see it.
