You're right should be c-record and the stem looks a little bit short, too. I was blown away initially tho because of the colour scheme with the golden wheels + the chromed rear stays & lugs
O but I agree it's a fabulous frame. I live 5 km from the Ghent track and I just should stop buying road bikes and invest money in/ swap my Trek T1 for a decent steel trackbike. Used to have a steel Merckx years ago but sold it for... 150 euro...
That Merckx has the wrong parts to get 10/10. Looks like eighties parts while rest is nineties (that colour scheme is mid till late nineties I guess)
