Listing it conservatively as early 20th century / likely pre-1927, rather than an exact manufacturing date.CONDITIONVery good vintage working condition.The tool shows normal signs of age and use, including some wear to the original finish, minor surface marks and patina. The Starrett markings and graduations remain readily visible.The rule appears straight and the protractor head is complete and moves easily. Please examine all photographs carefully.
