This is a super nice, clean post WWII vintage ratchet spiral screwdriver with the rapid return spring! It is marked "CRAFTSMAN WEST GERMANY" on the main nickel plated shaft.  There is also a mark "GERMANY 6903" on the chuck.  We are also including a magnetic hex bit adapter and a few Phillips bits with this nice screwdriver.  The adapter holds the short hex bit that you can purchase at any hardware store.  This screwdriver is medium size chuck diameter that Stanley made in regards to tooling, or the tips that fit into the chuck, they are the .280" (9/32)" shank diameter size. The screwdriver can be used with any of the (2) slot bits, that are included, or others you may acquire. There is very little wear on the screwdriver, about 98% like new, with one tiny spot of missing nickel plating on the main shaft, and it's minimal. In very good mechanical condition also. This one has a rapid return spring that extends the spiral shaft outward automatically (when unlocked).  This feature can be turned on or off, or can be locked in the closed position to use only the ratchet system as an option.
