Back then frame-builders expected the retail shopkeeper to do the final chase and face, of the frames ..
and then the customer picked the components to be fitted .... you might re check the head tube ream and face too ...
So the Campagnolo, or VAR, etc, tool kits were to be in a bike shop's tool collection .
if you go for a Phil Wood BB then thread chasing without the facing would leave the paint. their lock rings are entirely internal to the BB shell.
