i am not really concerned with the worth of this bike....i feel what i paid was fine and have no interest in selling it.....my problem is that i can't seem to find any information on a date of production....

assuming it was a custom build...it has no serial number.....and honestly no identifily marks other than 'Ron Cooper', a cinelli bottom bracket casing and campy drops.....its a dream to ride and beautiful bike....

i'm just wanting to know any information as to the basic timeline in which it may have been built

some pics....

(mine is the white one)

perhaps someone here might notice a consistency in the lugging/writing style..etc etc or if not perhaps point somewhere where i may be able to find some info....

thanks
