From memory at least, it certainly looks like the Topline I have (from a T-Town swap a couple years ago), and what I recall from my bike shop days. Early 90's. Very light, very pretty, but somewhat fragile by reputation. I even have a note tucked in the box with the recommended spindle/axle length, if anyone needs it. HOWEVER, mine takes 130 rings and the eBay set has Campy rings! I don't recall the Topline being available in 135. SO ???????
The Stronglight Ironlight also uses 130 and does not have the fifth bolt hidden by the arm.
I have both at home, so I'll compare to mine tonight.
