I find on my hard disk this viper mesh. I dont remember when and where I find it, but I've download it somewere years ago.
It is an .OBJ file complete with all the textures. It have also the internal display and the joystick. The models seems to be a low/med resolution model, perhaps for some kind of game (a flight/combat simulator? A "total conversion" MOD?).
Have you ever seen this mesh?
It is strange because it have the front of the engines rounded.
Here is a quick render in Bryce. If you want I can do a render at the same angle of the other Vipers on your Comparison Chart with a white background.
Just tell me
