Although the OP has already passed on the frame, I'd like to comment.

I don't think it's crash damage. The tubing isn't bent. Crashes don't crack tubing without bending first. From my experience, cracks (if indeed that is what it is) are from an overheated tube and stresses from them.

I've seen lots of super close-up pictures that people post and others swear they know what it is wrong, but it turns out they aren't. I've had a lot of frames come through the Atelier that many have declared to be toast based on pictures that I've been able to save with some loving persuasion.
