these are the very latest after many attempts at creating UV / Textures / Paint within Blender. Haven't got it down to a science, but, feeling good project finally back on track.
Managed to further tweak the GP38 today. Worked on interior colors, went with brown seats, black control-stand, liter shade of green on walls, (though doesn't look it in the snapshots. Continued to color various parts etc. Adjusted verts, scrapped various shapes not needed, little of everything, everywhere.
