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.
