This slide rule deals with tape measures (made from various materials) and corrections due to sag, tension, and temperature. I used the Google Translate App on each page and can send those images through messages to anyone interested. Just send a message to me. The original price was 3,600 Yen. The slide rule is made of plastic and measures approximately 12 3/4 inches long by 1 3/4 inches wide.
