The number "32" is printed below the three-inch mark, and the wooden part of the rule is marked: B. K. ELLIOTT Co. PITTSBURGH – CLEVELAND. It is also marked: R. S. C. It is also marked: U.S. ST'D.
Theodore Alteneder began making drawing instruments in Philadelphia in 1850, and the firm remains in existence as a manufacturer of photoengraving equipment. Byron Kenneth Elliott (b. 1870) opened a store in Pittsburgh in 1897 that sold drawing, surveying, and optical equipment. The shop closed in 1980. The donor's father, Robert S. Condon, used this instrument.
The date for this object is uncertain. Theo. Alteneder & Sons made a 6" opposite bevel scale with white edges and these divisions as model 2232 from 1940 (when it cost $1.35) to at least 1958 (when it cost $3.25). However, according to catalog illustrations, the company mark during this period had the firm's full name around a circle, while this object has only "Alteneder" in a straight line. The scale does not appear in the 3rd, 5th, or 1948 7th editions of B. K. Elliott catalogs.
