not sure how it might appear on your browser but the first pic is the blaze on, i think only newer colnago models have blaze on, 2nd picture is the top of the bottom bracket where the words colnago appear insteal of the clover which i see commonly found.

3rd picture is the bottom brack with the clover and the word colnago stamped on it.

finally 4th pic the seat stay colnago. the paint looks titanium.

columbus acciaiao specile or something like dat, columbus special steel. ,,, and the other one which says something strength guaranteed after the translation.

the parts of this bike are all normal shimano parts.

also i tried on my friend's bike and fell in love with it straight away. what might be the value of this frame? it rides really well, responsives is great compared to all other steel bike i ride. i've tried the schwin, saronni, olmos, but nothing has beaten this bike, i'm so tempered to buy the bike from my friend. this might be my only chance as well to own this expensive bike.
