I'm evaluating the condition quite strictly (considering the tire condition and some claw marks on the cord). Used only during the Showa era, and stored long-term until now. When I extended the cord for the first time in decades, I found a claw mark-like indentation in one place, like a winding unevenness. (I noticed it after close inspection). This 4.5m type has a different shape for the cord insertion part compared to other types. Thank you. I have pulled out all the cord and confirmed that it is working.
