Good work Jerry. Looks like the panel is another part that Trumpeter slightly boobed on - perhaps a later, civilian model? The central area of the panel, as shown in the pic I posted, should house 'George', the autopilot. (that's the part displaying the two large instruments, immediately above the throttle and pitch levers). These are predominant on all military C-47/Dakotas, and on those in civilian service even up to the late 1960s.
But, little will be seen through the cockpit windows once assembled, so no problem.
