Early on here I was labeled a 'lug Nazi' based upon my reaction to the mere sight of these lugs. Indeed, there was stress in 1973. Since the statute of limitations has passed, I spent over a week holed up, with the flue, in the Howard Johnson's Motor Lodge in Seacucus, NJ, testing, mostly, Supercourses, for frame integrity. More than a few went through the line without the internal brass charge having been placed in the tube, resulting in a frame held together with nothing more than the pins holding the lug to the tube.

Given that this frame is still intact, 40 years on, it's probably OK. That said, I'd look carefully for signs of paint cracking at tube to lug joints, especially at the head tube...
