Hey jacek! Greyleader was actually a different person who appeared quite briefly, made some interesting posts, and then deleted them and disappeared. Unfortunately, the one model he did deliver to us was an Action VI (he didn't know we already had one in progress and only posted about it when it was already done IIRC).
His version has a full set of textures so we'll probably end up using it, but you are of course still on the team and in the credits, and we would definitely still appreciate your help! If you feel like lending a hand but don't have any new ships of your own, we have a number of models awaiting conversion (zookeeper has been concentrating on coding lately). Anyway, glad to see you're still around!
