Abstract
An inventory control board includes a housing in which a series of front-to-rear spaced transparent sections are provided. A series of slots are formed in the housing beneath the transparent sections, and a series of shafts corresponding in number to the number of slots are rotatably mounted in the housing each such shaft being laterally spaced from and in alignment with one of the slots. Each shaft carries a pair of drums for rotation therewith, and windows are located in the housing above each of the drums to afford visual access to indicia carried by the drums.
