Matthew- Might have been a repaint. And decaled with the shop/team name. The shop made most bikes with the Hellenic seat stay style. Some of the one's that I made had unique braze ons and pump pegs. If you see one of these let me know.

I recently came across a Nuovo Record equipped bike badged "Cyclery North" locked up to a fence here in Brooklyn. A nice royal blue color with red and cream decals...Only upon closer inspection, it had "Pogliaghi" stamped onto the stay caps and "PSM" on the seat lug cluster. Yes, I went into all surrounding business. Yes, I found the owner. No, he would not sell me the bike.
