Other changes were to where the cabling snakes into the open parts.
I cut away the surface piping and laid fresh stuff that
would run into pre-drilled holes in the detail cavities.

if you know the kit of old from when it was first issued with lighting,
the big box area at the rear held the batteries.
Far be it from me to knock a design feature so that is
where the batteries for the lighting on this puppy ended up.
