Where'd the models go?

I was wondering where the old Catapult, Seige-watever-it-was, priest, etc., models went, if they're still in some file in the depths of my computer. I liked the old catapult. and was thinking of implementing it in a new map. Ne1 no where the hale it is?

Don't know where it is, but when you choose the model for demolisher, you have to set the box on the Extra Versions tool thingy in the object editor, to Reign of Chaos instead of The Frozen Throne

The priest is the same, he just has a different skin.
