So I picked up this bike today, and the seller believed it to be of English heritage. I haven't pulled it apart enough to check threading of the headset and BB, but I'm including some pics for help with the ID. The seller bought the frameset from CycleArt, who had repainted it. I asked him if he thought CycleArt had done any framework, but he didn't think so. Still, the internal cable routing, downtube shifter mounts, and two sets of bottle cage braze-ons seem some indications it was upgraded prior to repainting. There are no holes on the headtube for a headbadge. Any ideas?
