Contains C, D, and B standard scales.
I recommend using a brim when printing, as I got a little bit of warping without it.
Before assembly, I did very light wet sanding of the main cylinder and the insides of the small rings with 1200 grit sandpaper. I then rubbed the innner cylinder surfaces with paraffin for a smooth-turning slide rule.
