Questions about castles and hunchbacks...

[J.MorganKuberry]

Hey,
Does anyone happen to know the length of the tower and wall sections of the Warhammer Fortress model? I don't want a whole fort, just enough pieces of one to divide my tabletop in half, trying to figure out if a single wall and gatehouse will do the job, or if I'll need a tower as well to fill out. If I end up needing to order 3 pieces of the fort, I may as well buy the whole thing.

Also, I'm looking for a good model to use as a 3rd "dreg" in Mordheim. I have the 2 that GW put out back in the day, just need a 3rd to max out my heroes for that warband. I know the Luthor/Gunther the Hunchback from "Catacombs of Terror" works great, but everytime I find one of him, he's priced sky-high due to collector demand. Can anyone recommend any other good 28mm "Igor" types to assist my necromancer with his foul experiments?
