Just to clarify - that's not an Inter 10. The paint says 'Inter 10.' The dropouts are correct for Inter 10. But the geometry of the frame differs quite a bit from an Inter 10. No one has been able to determine it's exact lineage. Best guess was that it may have been a special-order job, but they backed out. It was sold as a one-time deal from Puch to Puch's distributors. It came through Sheldon Brown at Harris Cyclery. No name was given for the frame.
