Dish wouldn't twist it off center though, dish would offset the wheel right or left in the fork. I think the OP's got it. Sounds like the fork is twisted, or one of the sides of the fork is bent. On old frames this is easy to fix but difficult to fix well. Sheldon Brown's site has a good walkthrough.
