Unearthed during the year-end cleaning at my parents' house. This is a slide rule from the Showa era that my father bought a long time ago. ◆HEMMI Slide Rule Body: Approximately 12cm With leather case The leather case has some peeling. The main body shows some dirt, but it's in relatively good condition for its age. Please examine the condition carefully before considering a purchase. Please understand that this is a retro item and has been stored at home for a long time. #ShowaRetro #SlideRule #Hemmi #RetroStationery
