| Further comments | There is no manufacturing date on
this slide rule, but printed on one of the side is the character "S". I
do not know what it means. Not visible on the photographs is a logarithmic scale on the bottom. The addiator on the back is different from my other addiator slide rules. Normally there is a handle on the top that you pull to zero all positions. On this rule, the handle is recessed and has to be moved with the stylus.
