This is a GRAFLEX Speed Graphic large format Camera used by the US Military, probably Army Signal Corps.  Made in Rochester, NY.  I think it dates to the mid-1950's but stand to be corrected.  Serial number is 904116 on the body.  Measures about 7" by 8".  Black leather strap on the side. Camera is covered with military OD Green material.  It has a KALART Rangefinder on the side.  Lens is a Wollensak Graphlex Optar 127mm  f/4.5 No.G10989. Black folding bellows.  It is MISSING the original plaque that was riveted on the back identifying it as Signal Corps Cameral.  I am not an authority on these cameras but it appears otherwise complete and in excellent original working condition and is sold on that basis.  Great example of a Military Graflex.   Guaranteed to please the new owner or I'll buy it back.  Check my Feedback.
