These two are at 100 pixels per inch, from a model L. First, the top scale, number 430, with both linear and logarithmic sections (the linear section is for taking logarithms, and the logarithmic section is for multiplying and dividing--both are used in conjunction with the lower logarithmic scale, number 429, shown in the picture after this one):
Click on either picture to get a 300 pixel-per-inch version of the same image (takes a lot longer if you're on a modem line!).
Next is scale 429 from the same model L. I included the chrome-plated handle, which makes all kinds of nice color effects as it is rolled along the scanner and not kept in precise alignment with the lights and color sensors. The cursor's "hairline" mark and dimple are visible at the top of the picture.
