I have one myself which I use regularly but my frame is a bit different than yours - grey colour and maybe older (its a 60 x 59). I do not have on the frame itself the fittings for the brake cable or deralleur cable nor for the derailler shifters - the fixations had to be added (screwed on the frame).
The bottom of the back lungs are also different.
Very very light but quite stiff on some roads !
I really love it and it is filled with full Shimano 600 set (not campy) and 100 % original.
