It features a laurel wreath design and the number "23," suggesting it represents years of service or meritorious service within the association. The back has a screw-type fastener, indicating it was made for the formal uniforms and military attire of the time. There are scratches, discoloration, and dullness due to aging, but it retains the atmosphere of the pre-war to wartime period. The detailed history is unknown, so please review the images and consider accordingly. Recommended for collectors, research purposes, and those who enjoy military and retro items. *This is an antique item and is sold as-is.*
