I'm just saying I haven't seen one (and measured it myself) that had a 22.0 quill, but the fact that there were some Mondias and at least one Motobecane Le Champ that had one reinforces my second point: I haven't seen it all. They (3TTT) are an Italian brand...we know at least one other Italian brand (Cinelli) offered a (rare) FR quill stem.

I suppose that a 26.2 post might be credible in a frame with all this other "bling" if it had:
1. a fastback style rear that required a brazed-in shim (ala Cinelli SC).
2. used a plain gauge 531 (or another brand) seat tube (hard to fathom this given the not-huge size and apparent high-quality of frame), and even with this the "more common size" was from 26.4 to 27.0, IMHO.
3. was metric 531 tubing (OD of the tubes will confirm/deny this)
