Collectibles-General (Antiques)/Canadian fabrication scale


Hi, i've brought an antique scale ten years ago labeled of "The Computing Scale CO - Toronto" and i would like to learn more about it, rarity, possible yearling of fabrication, etc. So i've made few researches on the web and found ur address. Thanks for further info, i send a picture attached, let me know if any additionnal information is needed.

Sorry for spelling, english is not my daily language.
Have a nice week.

Hi Marc,

The Computing Scale Co. was incorporated in 1891 in Detroit, Michigan.  In 1900 Dayton Moneyweight Scale Company and Detroit Automatic Scale Company were acquired by Computing Scale Company. By 1912 the company, with offices in Dayton, Detroit and Toronto was acquired by Computing-Tabulating-Recording Co. which was renamed IBM in February of 1924.  The History of IBM may be found here: and here: .  Based on these facts your scale was most likely manufactured by the company in Toronto between 1900 and 1912. Most American collectors are not so interested in Canadian fan top computing scales due to the cost of shipping.    Retail value might be $150-$300.

Hope this helps.
