Most old-school road tube sets were .9/.7 wall would give you a 28.6 post if you put the ST in upside-down. Also it doesn't look like anyone touched the windows on those lugs either. I've said it before and I'll say it again, just because it has lugs doesn't make it special. best, Brandon"monkeyman"Ives Vancouver, B.C.

I'm not aware of a single steel tubeset that ever had a .9/.7 seat tube. Almost all 531 seat tubes are .8/.5, (531 Pro is .7/.5, like 753R) so a 531 seat tube would give you about a 26.6 post size (or maybe even 26.4) if inserted backwards. A lot of Ishiwata tubesets had 1.0/.7 seat tubes, though, as did Vitus 181 and Columbus SP, so there are a lot of tubing choices that can give you a 26.8-27.0 seatpost requirement, when built correctly. Even a standard 531 seat tube, properly installed, but not reamed after brazing, could necessitate a 26.8 mm post sometimes. I agree though that this looks like a home- or framebuilding-class-built one. I was only able to view the main, small picture at first (his others wouldn't load). Now I've seen the rest, and yeah, project frame sounds very plausible (not too bad if it was a first effort, though). There is also no serial number of any kind on this frame, per the seller....
