Very good set of impact tools, manufacturers labels have been worn off. The last knew they were Chicago Pneumatic. But they have been sitting in garage for many years, Used in the construction millwright trade , there oiled up work very well, come with case that holds both the 3/8 air ratchet and the 1/2 inch air gun, plastic red covers are in good shape. Not beat up few small scratches. Not sure on max torque specs but I'm figuring a 100 foot-pounds or greater
