Sun Hemmi 130W Ahrend sealed Slide rule full set Japan 1970 Netherlands

This is the extend variation to the earlier normal number 130 slide rule. This 130W version is a complete redesign and comes complete with its cardboard container and is still in the original sealed plastic wrapper. This box, manual, slide rule and case are made in Japan by Sun Hemmi. But do notice that this one was specially made for Ahrend (and so branded on the back) Ahrend was (and still is) a supplier for office furniture and materials. The manual is in English . It has scales on both sides of the slider and the plastic curser with glass insert has 3 hairlines. Slide rule and curser are complete and everything is in mint, unused condition. Cardboard container is also complete, hardly any signs of storage. It measures ca. 29,5 cm or 11 3/4 inches. Check out the attached video on how to operate a vintage slide rule!
