As said you'll never tell from a picture. Plus I don't see how a turbo can be "as new" when its been removed from a 22year old car.

Just get yours rebuilt. Will cost a bit more but then its peace of mind.
You may find that turbo will be fine, it may only last a few miles or it might be dead already.

Had a friend who didn't want to fork out to get his turbo recon'd. He's probably spent more buying second hand ones every 3-4months when they give up
