    Object Details

    Description

    This 51-1/2" wooden T-square has a scalloped top piece attached to the handle by 6 brass screws. A hole at the end of the handle is for hanging the instrument. It has no markings, but paint and ink stains on the handle indicate it was heavily used. The dating of other objects from this donor suggests this instrument was made about 1900. Compare to MA.328396 and MA.328397.
