Super rare Fulton MX-6736/U US Military Flexible Shaft Flashlight - works great

Description

Here's a rare one for the US Military or Flashlight collector:  A Fulton MX-6736/U US issue flexible shaft flashlight.
This is one heckuva light: despite the obvious unusual flexible shaft letting you shine the beam through a 3/4" diameter hole, this 2 D-cell light has a clip for hanging, a spare bulb in the tailcap and a secret compartment for who knows what...maybe color filter lenses?? If you DO know, please let me know so I can add it to the listing!
This flashlight has light corrosion on the spring on the cap that does not affect operation and it is currently in perfect working condition.
Very unusual piece that I have never seen before and might not ever again if you win this auction!
Given this is a vintage piece, I'm selling it with no warranty or returns, so please feel free to ask questions and by all means please inspect the pictures.
