airship balloon dirigible 3d model - Aerostat.3ds... by sammeads

An early aerostat (circa 1900) created from various sketches from the era of such craft. After looking at all, I built this aerostat (aerostat meaning light-than-air).
Crafted in Rhino 3d 3.0.
This model took approxmately 40 hours to construct and texture.
I'm fussy about how meshes look, as I design for simulators, so the mesh construction of this model does not waste polygons.
For use in any program capable of using 3ds models.
