no they arnt but they have a look to them that you cant take your eyes off. Im suprised you found enough images to make a good drawing, those ships are fairly hard to find online
Actually, I have to disagree. Most pictures are fairly low-res, but taking a quick google look there IS quite a bit of imagery available. You're not going to get the detail like you'd get in a modern warship, but as Bombhead is proving it's certainly possible to make something better than what was already in the archive.
I imagine that the biggest problem was the rather small blueprint that is the only one online. Even so, that still gives you enough to at least eyeball the superstructure and hull.
