You're looking at the 1980's gray variation of the Operating Searchlight Car, #6522. It is modeled after the postwar classic No. 6822.
This one has the print for the Chicago Northwestern, CNW Railroad.
CONDITION: C-7. Tested and works. Complete and unbroken. Does show handling wear from being played with, mainly along edges; enlarge the pictures to see it up close. Pictures are part of the description.
