Headset tip -
In case you have occasion to service the proprietary Bianchi integral headset it requires the use of two horizontal pattern pin tools as made by Park or VAR.
Do not attempt to hold or turn either the adjustable race or the locknut with pump pliers or similar tools, even with cushioning. This will only gall up the finish, as we can see someone has already done to the locknut knurling in this photo:

The VAR pin tool Nr. 13 is a handy one to have in one's kit as it handles both horizontal and vertical pin holes. Its pins are made replaceable.

An acceptable alternate tool for adjustable races is the VAR Nr. 78 headset plier. It jaws a specifically designed not to gall finishes.

This headset employs 1/8" balls.
Bearing cups are pressed in to the ends of the head tube. Their inside diameter is nearly identical to that of the inside of the head tube making them difficult to knock out in the usual manner. If one has the Campag head cup removal tool, or similar, one can wedge a socket into its open end such that the tines will gain purchase on the edge of the bearing cups for removal.

Beginning sometime in the latter 1950's Campag started offering a headset in this Bianchi pattern. It is found on Specialissima model cycles of the 1960's era. Had occasion to service one - smoothest turning headset have ever encountered.
