This offer is for ONE only 'Sun Hemmi'

15 cm (6") slide rule No. 74

There are 2 versions of this rule and this is the metric version with a 14 cm metric measure on the top beveled edge.

I also have the other version, which has a 6" imperial measure and this is shown in a separate listing.  It has a 5" measure on the same edge, but is considerably rarer in this condition, as most of the 6" are older stock and only exist in this condition because the stock was not sold in rotation when the newer metric version came in to stock

Although these were manufactured in the 1960's (I have various dates of manufacture, one being 'QJ', so October 1966, although this date is the 6" version and some metric from 1969 and 1970), making most of them about 50 years old, so I have classed them as new because they have not been used and have been sealed away since manufacture.

I have a small quantity of these slide rules, which are in their original packaging, each with a 40 page instruction book (size 5 x 7"), leather case and the slide rule which is complete with its cursor, is still in its sealed polythene bag.

The picture shows an example in various stages of undress (I also have an unsealed spare, which I used to take some of the pictures).

The reverse of the slide (not shown) has S, S&T and T scales

The leather wallet is 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 leaflets 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 about 50 years.

The boxes were stickered with green end labels, some of which have flaked off in one piece.

This item is rare and in this condition, is extremely rare.
