Forgot to say, that's a beaut !!
Regarding the shifter bosses on the downtube, they look like they still accept the '90's > bosses for cable holders - the 'old style' shifters on the downtube and the later '90's > lever changers use the same type of braze on. That only changed much much later on where you see a little round braze on only just bigger than the diameter of the cable outer and is much neater as that negates the need for the alloy body that the adjuster screws into. (Does that make sense
)
You might find your frame is either '92 or '96 i've never heard of the olympic being made only in the Olympic years but that does sound very plausible.
As there were so many different colour schemes it's hard to track frames down in the sparse catalogues that were produced as they were hand painted and unique in a way. Solid red was used for many years too but I'd say your frame is definately one of the two years above. The frame number on the rear drop out generally does not unfortunately relate to year of manufacture, indeed some don't even have one! When searching the net for the info I see many questions asking and when the number is presented the trail dies - the number rarely means anything. It's my assumption that with colnago frames unless you've seen your colour scheme in the catalogue or have firm proof when the original owner bought it then you have a window of a few years of which you can never reliably narrow down.
