Dahan - The simple answer - that has been given before, I might add - is that very little is known from those eras. Make it up as you go along. As for the whole psych thing... Just learn to check your refs. If there's not enough information when it's all said and done - make shit up. Just do it in a plausible, believeable manner. This holds true whether your making a High-Res Hornet, a McAuliff era carrier, or a custom mod. If you do it well, people will take it as fact, and you'll have done a good job.
And don't fark with psych. He'll take your pretty little beach house and turn it into kindling - from the pilings up.
Good luck with whatever you're working on.
