We used the same stats as in the original games (WC2/WC1), adjusted by some global scaling factors used in Standoff (ie, all damage, armor and shields are multiplied by 20, because a ship with "80" armor is fine in WC1, but in WCP it would instantly die from any collision even at 10 kps).
Note that these stats don't always match the source material for those games... we used the actual stats from the game files, not from the manuals.
Oh for the guns....uh you will need wcpedit for that.
Edit: here are a few
Note: damage will be 20x that listed for WC1/2 and 2x what would be listed on the website
One thing I note, though, is that a number of these gun entries have the same gun name, some with different stats, so I really can't tell which of the entries are for fighter guns and which are for turrets without some heavy cross-checking with the fighters themselves.
