BACKGROUND.
The
Fowler & Company of Manchester, England, established in 1898 was a notable manufacturer slide rule calculators in a pocket watch format. In business from 1898 to 1988, Fowler made a large variety of calculators, although the labor-intensive nature of its manufacturing process produced expensive instruments that never sold in large numbers.
Fowler had studied mathematics at Owens College.Manchester in the 1870s. He became editor of the journal
The Practical Engineer
in 1891, which led to him starting the Scientific Publishing Company in 1898. That year, his journal
The Mechanical Engineer
published the design of a circular calculator operated by moving fixed pointers over a revolving dial. Following these achievements,
William Henry Fowler (1853–1932) and his son, Harold Fowler, took out several British patents for improvements to circular calculators between 1910 and 1924. The first Fowler calculator with two knobs on the rim was patented in 1914. In 1927, Fowler & Co. introduced the Magnum UNIVERSAL Calculator, which extended the scale length to 50 inches.
Using the reference valuation and information guides* similar to the grading of fine tools, this vintage
FOWLER UNIVERSAL CALCULATOR With Custom Leather Case Holder
might be graded in a
FINE
+
rating in accordance with the criteria:
FINE:
Tool is completely useable; metal is 90-100% and may have a trace of rust and some dark patina; wood 80% original or old finish, smooth surface and edges slightly rounded; minimal wear and no repair; maker’s marks, if present, are clear and easily legible.
NOTE:
Grading is an art and not an exact science thereby creating the need for sound judgment. To address the wide scope of possibility, most grading guides are purposely vague and somewhat subjective in nature.  Grading combines personal opinion, subject matter research, past experience, and knowledge to allow each individual a distinct perspective in assessing reasonable or acceptable condition. Value determination comes with the rarity, customization, existing item condition as derived from review of available pictures, questions to the seller, and study of pertinent reference materials. Multiple pictures taken at different angles and available lighting may offer the only possible visual overview of specific features along with the revelation of both the highlights and failings to support a sound decision whether to participate in this online auction.
