    I still have a similar one from the 1950’s. It’s called ‘Wizard Calculating machine’ Add, Subtract, Multiply, Divide.
    Basically you insert tip of steel stylus in notch beside number and pull down to bottom. Multiply by sequential addition and
    divide by sequential subtraction. No batteries, ha! Goes well with a slide rule.
    Best regards,
