Here is a link to a virtual N 3-T Pickett sliderule, the same one I used to do the rhumb line calculations, so you can try it out too. Notice that the error in the scale markings for "82.5" on the tan scale is shown on this virtual sliderule.
Here is a link to the SlideRule Museum. Click on "slide rule scales, build your own SR" to download the Ln scale.
