The seller discloses two "putjes" which are little dents. The components on the bike means that they have been swapped out as they were not current to the time this bike was built, so you can expect that the first owner used it hard and then sold the frame alone onwards. This in itself is not terribly confidence invoking. I have some friends in Antwerp who could check it out in person, but I wouldn't waste my "favor" token for this bike.
