All of the sockets are either Plomb 7/8"s to 2-1/2"s (most of them), Proto La, one P&C, and one regular Proto. Has two breaker bars, an eight-inch extension, and one 1" drive socket (2-3/8"), which is not the biggest socket! What is interesting is it a mostly black oxide set. Never seen that before. Now I need a black oxide ratchet...
