1. On the front this slide rule has "conventional" scales but it can hardly be described as a conventional arrangement: two tan scales and no sine, three log-log scales but these are LL03,LL3,LL2.
2. The most interesting aspect of this rule is its chemical scales. These are shown below.
3. The text of the manual can be found here.

My thanks to Dr Jon Iza who provided the images of this rule and who scanned and formatted the text of the manual.
