STARRETT 12" NO. 4 COMBINATION SQUARE - PROTRACTOR, CENTER FINDER

12" No. 23 (also marked No. 4) rule with three heads. The scribe is still attached to the square. One of the two level bubbles is missing, but these are easily replaced. Nice early stippled finish. Great square, the usual Starrett quality. Perfectly functional as is or it could be polished if desired.
