This is a nice vintage North Brothers YANKEE No. 30 screwdriver.  It comes with a common (straight slot) screwdriver tip.  This has been cleaned and lubricated and works perfectly.  This is the kind you have to push and pull.  It ratchets on or off and can be locked so it does not extend.  There are 4 patent dates on it.  I can make out 2 of them to be APR 16 95 and NOV 2 99.  This is not only a great collectable, but it will serve you for many years to come, as it was intended.
