Thank you for your responses.
I checked it out and decided not to buy it. Well, the bike was built for 650 wheels. Frame was lugless and in IMO, not as nice looking as a standard lug frame. The chain and seat stays just looked kind of 'clunky'.
The seller told me that the tubing was oversize Tange but I don't recall seeing any Tange stickers. The rear dropouts were chromed and stamped Tange.
That's it. The search continues...
