Interesting, probably Aristo build, school slide rule with the box, container and instructions. Marked HIV / Intra model 1055 Tertius II from around 1970, made in Germany. It is ca. 32,5 cm or 13 inches long. It has like the Arsito-Scholar 6093 with 10 scales on the front. There are 4 (not 3 as Aristo) on the back plus the cm / inches scales. It is made of plastic, as are the the slider and the case, there has been a school class mark engraved on one end (like “CS”). Box shows clear sigs of storage. Great desk piece but very usable as well. Shows minor signs of use only. check out the attached video on how to work a slide rule or read the article about collecting slide rules here.
