Hemmi number 74 Bamboo base 6" Imperial Reitz Slide Rule. These were manufactured in the 1960's (there are various dates of manufacture, one being 'QJ', so October 1966), making these rules over 50 years old. They have been classed as new, because they have not been used and have been sealed away since manufacture and are known as 'Old new stock'. They are in their original packaging, each with a 40 page instruction book (size 5 x 7"), a leather case and the slide rule which is complete with its cursor, is still in its original sealed polythene bag. The main picture shows an example in various stages of undress. . The reverse of the slide (not fully shown) has S, S&T and T scales The leather wallet looks as fresh as the day it was made and the slide rule itself is also faultless, as it has been sealed in polythene. There is some discolouration on the right hand side of the first page of some of the instruction booklets and a little on the cover. This has been caused by both its age and the leather being in direct contact with the booklet for over 50 years. The outer card boxes are a little scruffy. This item is rare and in this condition, is extremely rare.
