Vintage 12” Combination Square Protractor Union Tool Co Orange Mass Machinist. Used fine condition with a nice aged patina - see my photos. The inclinometer part is not marked by Union but came with the other parts and matches all the other examples I have found, it possibly could be Starrett. The set came together and I am sure that is how it was always used.
