Tough to find correct postwar Lionel O Gauge 3424-75 Low Bridge Signal Non-Overstamped box.  Base and track contacts have surface rust (easily upgraded), tell tale pole has no marks at base or broken fingers.  Original 3424-95 5-57 instructions sheet and correct 3424-97 components envelope for "1" of each part, not "2".  Box has minor wear at flaps, otherwise box is beautifully bright, clean, square and solid.  Fantastic addition to a top shelf collection.
