Metal Portable Rolling Contact File
This vintage portable contact file has a solid industrial-like metal casing and is operated by rotating a metal knob on its side to turn the paper reel to the desired letter/contact. There is a also a red line that runs diagonally through the paper roll (from left-to-right). The red line is used to indicate which letter you are currently on (i.e. the red line is on "G"" in the photo above). File is in very good vintage condition and comes with original box. The only writing on the paper reel is the first slot of letter "A" which someone has written "Allday". Curious.
