Straight Edge Signed I. R. C. Co.
date: label: date made
content: 1926–1961
notes: label: Description
content: This undivided black hard-rubber rule is beveled along both long edges. It is marked: I. R. C. CO. (/) GOODYEAR. Scratched on the back of the rule is: Brereton. IRC, or Inoue Rubber Company, was established in Japan in 1926 to make bicycle tires and tubes. The reference to Goodyear is likely to the manufacturing process pioneered by Charles Goodyear and not to the Goodyear Tire & Rubber Company. Brereton was presumably the original owner of the instrument, which was acquired by the Museum in 1961. Compare to MA.327306.
