Dave,
You're right, it would take a tremendous amount of work even with a very sharp tool to cut off the rings on those lugs! There's a lesson there somewhere; don't let rookies take sharp tools to bike frames.
Also, as Richard mentioned, Masis have a champher inside the head tube that is cut during the facing operation. It is a Masi innovation if I'm not mistaken. It goes back a long ways. One might notice that more modern Campag. tools cut this champher; older Campag. tools do not. I think it was introduced at some point when it became neccessary to cut that champher to accomodate a new headset design; I'm not sure when. It must be pre 1982 because the tool case I have now was purchased then and it cuts the champher, which by the way is a great thing for the look of a headset; especially older ones.
