According to the fellow in the Framebuilding forum asking about what he should do about this headtube following the damage, both ends had been faced following a brand-new powdercoat.
Supposedly, the cups were not reluctant to seat properly - that's what gets me more then anything else. I only wonder whether the powder was cured at a temperature much higher then the 380 +/- degrees Fahrenheit usually used for the purpose, and in the process, weakened the metallurgy.

Wasn't me.
