You are looking in the wrong places.

Is the seat tube chain oiler 7mm? Then definitely Bianchi. The odd thing I see is the fork crown. It is atypical for Bianchi. But it wouldn't be the first time I have seen something different. On the other hand, it could be a replacement.

No doubt, a nice frame. Once you get it apart, considering the rounded cup flare of the head, one the head cups will probably be stamped, I'd guess Brown & Wilkes......
I have just been introduced to a Bianchi integrated headset, so plead ignorance. Are they 4 cup head sets?

Bikes: A Blue One and 2 Green One's, then there's the Yellow one. And oh, yeah, a Black One. Did I mention the Red One?

I wont get into early frame styles and parts suppliers. As today, one cant say that the parts make the marque. Then, as today, parts change easily to the next best flavor of the week or what the trend is. Im just saying that of my 7 pre and post war English bikes, this frame displays a lot of English attributes. Oxblood color, Box Pins, Triumph transfer, fishtail lugs, four cup headset. Triumph was not always a Raleigh bastard child. Early on, they were a contender with some really nice frames. Why would someone put a triumph transfer on a Bianchi? has anyone ever seen an oxblood Bianchi? My 39' Armstrong has those exact Lugs, English made. Phillips supplied frames with those lugs and so did Hercules..... The seat post bolt pinch would be unusual for an English bike for sure... Whatever, its really not the point is it?

If a person were to take the headset apart and loosen everything there, all of it, If it indeed did start out a clip head steerer, the bight there may be the issue. The Italians and the French used clip stems occasionally also, it was an early European thing, mostly English though. As parts style and function progressed clips stem were often removed and replaced with quill style or barrel swedge. I've had a swedge stem placed high enough in a clip style steerer that it deformed the steerer when it was tightened. This pushes out the "T" cut area in the steerer and the wedge or barrel from the stem gets caught in the deform.

.... or it could just be stuck, whereas dipping in OA for a day or so should solve the issue.

This is the lateral view of the fork crown. I think that this crown was also used in Tipo M up to 1932 and the first Saetta in 1933.
The oiler is 7mm diameter.

The frame has two integrated cups, and the bearing balls race goes inside. The headset has only two removable cups. And the upper removable cup has "Bianchi 38" engraving.


The head tube, and the frame itself is just like my other 1937 Bianchi. Also the fork is the same, except for the fork ends. In the picture bellow you could see the chromed removable cups. This one has "Bianchi 37" engraving.

Monday I started using OA. After one day, the liquid was greenish. I washed it with water and tried to remove the stem. It's still heavily stuck. I replaced the OA and let it rest another day.

I would switch to penetrant, I have never seen Evapo-rust or OA dig in for a very deep dive, maybe add some moderate heat, heat gun or hair dryer and cooldown with dry or ice water to maybe shock it loose.
