Diskussion:Tom Thumb Adding Machine


The Tom Thumb adding machine is a re-branding of the Baby Calcuator. The Tom Thumb appeared in early 1959. There is no connection with the Tom Thumb of Western Stamping Co of Jackson, MI. This re-branding of the Baby was done perhaps because of price competion from the German calculators - primarily the Wizard. The Baby sold for $2.95 and the Tom Thumb sold for $1.97; however, the Wizard sold for just $1.00 (sometimes less). The last ad in Popular Mechanics for a Tom Thumb appeared in the January 1963 issue.
