![]() an Avery letter scale with many weights | William Avery became the owner of a weighing scales company in 1813 after the death of his cousin. Together with his brother Thomas Avery, he continued the business. From 1818 under the company name W & T Avery. It remained a family business for a long time; in 1894 it became W. and T. Avery Ltd. From 1900 onwards, branches were also established abroad and other manufacturers of weighing scales were acquired. For example, Henry Pooley and Son in 1913, as well as Parnall and Sons. In 1922, De Grave, Short and Co. also joined. In 1979, the Avery concern was acquired by General Electric Company (GEC). In 1993, Berkel was acquired by GEC and subsequently merged into Avery-Berkel. In 2000, Weigh-Tronix purchased Avery-Berkel, and the company was given a new name once again: Avery Weigh-Tronix. | ![]() back of the letter scale |
strange assortment of weights, namely a number in grams: 120, 60, 30, 10 and 5, a few in grams: 20, 3, and 2, and a few in ounces: 2, 1, and ½, see the photos.
The scale base is 19.7 x 11.8 centimeters, the weight plateau is 4.1 cm round, and the letter plate is 5.4 x 6.7 cm. The letter scale is 9.4 cm high. The recesses for the weights have a felt coating. The scale rests on four donut-shaped feet. The 1903 Avery catalog lists a letter scale with number 371 ("brass letter weigher for private use") that resembles this letter scale, but its fixed, stationary frame has a few extra protrusions at the bottom. Strangely, in the 1916 catalog, Avery presents a letter scale with a distinctly different fixed frame model with the same number 371; see the bottom of this page. Below are some more images of this Avery letter scale.
