- Initially a manufacturer of boards for measuring timber and then of steel measuring tapes, the Lufkin Rule Company took that name in 1885 and moved from Cleveland, Ohio, to Saginaw, Mich., in 1895. By 1903 Lufkin was the largest manufacturer of steel measuring tapes in the United States. Around 1915 the firm began importing boxwood folding rules from central Europe and made the rules itself once World War I cut off its supplies. While Lufkin had a model 651 (formerly 68) that it advertised from the early 20th century into the 1950s, model 651B only began to appear in 1916 and disappeared by 1925. Twelve of these rules sold for $2.50 in 1916.
- Lufkin president Fred Buck received the patent noted on the instrument for an improvement to the joint. Thus, this rule dates between 1918 and 1925. Cooper Industries purchased the company in 1967, closing its factories but preserving Lufkin as a brand name. An earlier Lufkin rule is 1985.0817.01.
