buy it! Funny that this Concorde has Ciocc piercings in the headlugs: the factory wasn't even half trying to disguise the connection! it has no tubing decal. but my guess is with the chrome rear triangle and other details it has to be a least Columbus SL, possibly SLX. It will be a great riding champ (unless there's some hidden damage, but I see none) and probably from late '80s. If it fits, you will not regret it...buy...
