[Milsurplus] What Plane?

[Hue Miller]

What plane is this? I'm looking at aisle photo, looking forward to pilots 
and
instrument panel. Sitting on top of the column with levers, between the 
pilots' seats
are left to right, 3-receiver SCR-274 control,  with transmitter control box
below, then next an ARN-7 control box. There is LOTs of big windows in this
view, nice all around 180 vision. Just behind the pilot's seat is a BC-348J
facing to rear of plane, no wall between this position and pilot's seat,
on stanchion at right side of BC-348 is the interphone/ radio selector
box, below it and to right side of BC-348 a tiny ledge with the
telegraph key.  This is circa 1946. C-54, or what?
