...if a description helps, the lug is definitely cracked, as visible in the third photo. The flip side of the crack in the fourth photo shows the interior surface of the head tube, opposite the crack, which extends to just about where the down tube section of the lug begins (where the lug changes direction, at the angle where the head and down tubes come together. The head tube interior is intact, and not deformed in any way I can see. The headset race sat in there fine on the bottom. Both those photos are of the lower head tube at the down tube junction.

But thanks. I figure I'll take it over to Steve Rex and see what he says. I'm not emotionally attached to the bike, and can always use the parts on something else, if it becomes wall art.

Was just wondering if anyone has had the experience before, what might have been the results. I do my own alignments, and have some experience with brazing/welding. Don't think I want to try it on this particular project.
