I have recently inherited this sword from my grandfather. He acquired the it while serving on the USS Barataria during WWII. My dad was over today and we took it apart so I could find more information about its origin and history. There were markings on both sides once we took it apart. It was kind of hard to read, so we tried multiple lighting and photo angles. We’d love to know anything about its origin and history. In particular, there is a red dot on the hilt and we have no idea what it is or why it is there, but it looks like blood.
