Menu Minder, A Recipe Calculator

This rotating cylindrical table helps a cook to alter the quantities of ingredients in recipes.
A three-column table on the left side indicates how quantities should be multiplied for a recipe with four servings to one with six or eight servings. The rightmost column (for four servings) has the numbers 1, 1-1/3, 2, 3, 6, 8, 10, and 12, with the numbers in the middle column ranging from 1 1/2 to 18 and the numbers in the third column from 2 to 24.
A second table show how one should alter the number of cups, tablespoons and teaspoons in a recipe to change it by a factor of 3, 2, 3/4, 1/2, 1/4, 2/3, or 1/3. The cylinder has knobs at both ends for rotation. It is enclosed in a brown plastic case with a clear plastic front that has a sticker attached to it. Two windows in the sticker show the tables.
A mark on the center of the sticker reads: MENU MINDER (/) A RECIPE CALCULATOR. A mark on its right edge reads; COPYRIGHT WILLE ENTERPRISES 1974. A mark on the back reads: MFG BY (/) PROTO PRODUCTION PLAS [. . .] (/) BOULDER COLO. The mark on the back is partly obscured by two of five magnets that will hold the Menu Minder to a metal surface.
