I went digging through my archives and came up with these C-47 photos from Vietnam. They are provided for interest only and probably have little value.

Me again and those really were tube radios (which is why they needed a radio operator.

To plot this we need a new set of numbers for the wing water lines. Guess what? Iíll have to approximate. First the flat portion:
At FBL 0.000 and Station 195.5 to 372.5 WL 115.00
At FBL 142.00 and Station 195.5 to 372.5 WL 115.00 (The engine mounts centered on FBL 111.00).
Now the Dihedral; At WBL 413.000 and Station 312.5 to 360.0, WL 160.00.
