I wondered that myself Pete. It does appear that the shell was bored to clean up the inside. It is possible to set a frame up on a milling machine once everything is brazed up and bore that b.b. shell to clean it up. I'm not sure this is the way this b.b. shell was done though because the chainstays and the seat tube appear to be de-burred before brazing. Either that or some serious hand sanding was done after boring the shell. Very nice work, either way.
