In 2005 I had Mercian build me a Vincitore SPECIAL frame with Reynolds 725tubes, I also had them paint it to my specs, It is indeed a fine frame built up with Campag Daytona 27 speed, I have ridden close to 30K miles on it, The difference in the special IS the bottom bracket lugs as pointed out, I also have a 1950 Mercian with Nervex lugs with LONG tangs that can be seen, along with my other bikes on Peter Underwoods FIRST CLASS web site http://www.classiclightweights.co.uk I did also visit the Mercian shop in 2004 they are a first class outfit very help full and full of knowledge.
