Object Details

Description

This 19" wooden T-square has a curved top piece attached to the handle by two steel screws. The back of the top piece has a ridge for positioning against a table. A hole at the end of the handle is for hanging the instrument. It has no markings. The dating of other objects from this donor suggests this object was made about 1900. Compare to MA.328396 and MA.328398.
