This is a beautiful large slide rule using the Rietz system. Due to the length it would be more accurate than the standard model 23R. I am guesstimating this one is from ca. 1940. Everything is complete, no cracks, chips or dings and in working condition and very large glass cursor. There are some signs of age and from normal use, some of the nickel plating on the cursor shows wear. A small part of the white laminate is glued back in on the centimeter corner side (shown in last picture). Overall in a good condition for it’s age, price matches condition. There are marks from storage on the corners of the original signed cardboard container and a decal from the reseller in Vienna, Austria. It measures about 58 cm or 23 inches wide. Check the attached video on how to work your vintage man tool : slide rule operation instructions!
