These profiles approximate knob vertical cross-sections, numbered by knob serial number, with dimensions of diameter (D) and height (H) in inches. The photos are taken with the knobs at a set distance from a digital camera, and mounted on a 1/4-20 screw. So the visual sizes are correctly proportional. But because of parallax and a slight pin-cushion distortion, a flat top or flat bottom will appear slightly rounded. Many knobs have very similar profiles, but all are slightly different, often depending on decorative and finger grip grooves. Actual sizes can be estimated by reprinting this page to the scale of the listed dimensions. On my screen, 0.80″ shows as about 1 inch. Your screen may differ.
More will be added as processed. Some knobs that are simply different sizes of cylindrical will be left out.
Many of the knobs between 22 and 38 are simple cylinders, made merely to show the iridescence of the wood, or lack thereof.
There were several similar knobs to 50, 51 & 54, differing only in size and decoration.
