Stanley Push Pull No. 7506 Tape Measure, 1935-1948

Stanley has made measuring devices from 1850 through today.

For a comprehensive study of Stanley measuring tapes, see:

"Stanley Tapes Measure the World" parts I, II, III, IV and V by Walter Jacob. 

The paragraph regarding the above measure reads as follows:

"By March 1935 Stanley had introduced the "target" case models-removable blade pull-push rules nos. 7406 and 7506. These rules were both six feet, with the no. 7406 (Figure 1) boasting a chromiumplated case with red and black enamel filled decoration. The no. 7506 had a gun-black steel case with red enamel filled design (Figure 2). They resembled a target, thus the name. Another term often describing these rules is a "bull's eye" rule.

These target tapes, patented by Austin Stowell of Stanley (no. D98,554, Figure 3, and patent no. 2,131,694, Figure 4a and 4b), were close-cased rules. These rules had a hubless design, which had a coiling medium of a double row of protruding spring fingers fitted around the inside of the case, against which the blade coiled. No. 7406 was permanently discontinued on 21 December 1942. Target rule no. 7506 was continued until 1948, when the tape was changed to a vertical read and the enameled decorations were eliminated (Figure 5). The case was redesigned in 1950."
